What is analytic mechanics and why is it important?




Analytic mechanics is a branch of physics that deals with the study of the motion and equilibrium of bodies under the action of forces. It is also known as classical mechanics or Newtonian mechanics, because it is based on the laws of motion formulated by Isaac Newton in the 17th century. Analytic mechanics is important because it provides the foundation for many other branches of physics and engineering, such as fluid mechanics, thermodynamics, electromagnetism, relativity, quantum mechanics, aerospace engineering, mechanical engineering, civil engineering, etc. It also helps us understand and predict the behavior of natural phenomena, such as planetary orbits, tides, waves, collisions, etc.


The main concepts and principles of analytic mechanics




Analytic mechanics can be divided into two main parts: statics and dynamics. Statics deals with the equilibrium of forces and moments acting on bodies that are either at rest or moving at a constant velocity. Dynamics deals with the motion of bodies that are accelerating due to forces or moments. Within dynamics, there are two main approaches: work-energy method and impulse-momentum method. These methods are based on two fundamental principles: conservation of energy and conservation of momentum. Analytic mechanics also covers topics such as oscillations and vibrations, which are periodic motions that result from restoring forces or moments.


Statics: equilibrium of forces and moments




Statics is the study of how forces and moments balance each other to keep a body in equilibrium. A force is a push or pull that acts on a body. A moment is a rotational effect that results from a force acting at a distance from a point or an axis. A body is in equilibrium if it does not move or rotate under the action of forces and moments. To determine whether a body is in equilibrium or not, we can use two conditions: (1) The sum of all forces acting on the body must be zero; (2) The sum of all moments acting on the body about any point or axis must be zero. These conditions are known as the equations of equilibrium.


Statics can be applied to various problems involving structures, machines, beams, trusses, frames, cables, etc. For example, we can use statics to calculate the reactions at the supports of a beam that carries a load; to find the internal forces in each member of a truss that supports a roof; to design a crane that can lift a heavy object without tipping over; etc.


Dynamics: motion of particles and rigid bodies




Dynamics is the study of how forces and moments cause a body to accelerate or decelerate. A body is a collection of particles that have mass and occupy space. A particle is a simplified model of a body that has mass but no size or shape. A rigid body is a special case of a body that does not deform or change shape when subjected to forces or moments. To describe the motion of a body, we need to specify its position, velocity, and acceleration as functions of time. To relate the motion of a body to the forces and moments acting on it, we need to use Newton's laws of motion, which are:



  • First law: A body remains at rest or in uniform motion unless acted upon by an external force or moment.



  • Second law: The rate of change of momentum of a body is equal to the net force or moment acting on it.



  • Third law: For every action force or moment, there is an equal and opposite reaction force or moment.



Dynamics can be applied to various problems involving particles and rigid bodies that move in one, two, or three dimensions. For example, we can use dynamics to analyze the motion of a projectile that is launched at an angle; to determine the angular velocity and acceleration of a wheel that rolls down a slope; to calculate the impact force and impulse when two cars collide; etc.


Work and energy




Work and energy are two concepts that are closely related to the motion of bodies. Work is the product of force and displacement in the direction of the force. Energy is the capacity to do work. There are two main types of energy: kinetic energy and potential energy. Kinetic energy is the energy due to the motion of a body. Potential energy is the energy due to the position or configuration of a body. The principle of conservation of energy states that the total energy of a system remains constant if no external work is done on or by the system.


The work-energy method is an alternative way to solve dynamics problems that involve changes in the speed or height of bodies. It is based on the work-energy theorem, which states that the net work done on a body is equal to the change in its kinetic energy. The advantage of this method is that it does not require finding the acceleration or velocity of the body, only its initial and final speeds. The disadvantage is that it does not give information about the motion at intermediate points.


The work-energy method can be applied to various problems involving particles and rigid bodies that move along straight or curved paths. For example, we can use this method to find the speed of a roller coaster at the bottom of a loop; to determine the height that a ball reaches when thrown vertically upward; to calculate the power required to accelerate a car from rest; etc.


Impulse and momentum




Impulse and momentum are two concepts that are closely related to the motion of bodies. Impulse is the product of force and time interval during which the force acts. Momentum is the product of mass and velocity. The principle of conservation of momentum states that the total momentum of a system remains constant if no external force acts on the system.


The impulse-momentum method is another alternative way to solve dynamics problems that involve collisions or impulses between bodies. It is based on the impulse-momentum theorem, which states that the change in momentum of a body is equal to the net impulse acting on it. The advantage of this method is that it does not require finding the acceleration or velocity of the body, only its initial and final momenta. The disadvantage is that it does not give information about the motion before or after the collision or impulse.


The impulse-momentum method can be applied to various problems involving particles and rigid bodies that collide or experience impulses in one, two, or three dimensions. For example, we can use this method to analyze the collision between two billiard balls; to determine the recoil velocity of a gun when fired; to calculate the impulse delivered by a bat when hitting a ball; etc.


Oscillations and vibrations




Oscillations and vibrations are types of periodic motions that result from restoring forces or moments acting on bodies. A restoring force or moment is one that tends to bring a body back to its equilibrium position when displaced from it. A periodic motion is one that repeats itself after a fixed time interval called the period. The frequency is the number of cycles per unit time, and it is equal to the inverse of the period. The amplitude is the maximum displacement from the equilibrium position.


when a body oscillates with its own natural frequency without being acted upon by an external force. Forced oscillations occur when a body oscillates with a frequency other than its natural frequency under the influence of an external periodic force. The frequency of the external force is called the driving frequency, and it may or may not match the natural frequency of the body. When the driving frequency is equal to the natural frequency, a phenomenon called resonance occurs, which leads to a large increase in the amplitude of oscillations. Oscillations and vibrations can be analyzed using various mathematical tools, such as differential equations, complex numbers, Fourier series, etc. They can also be modeled using physical systems, such as springs, pendulums, masses, etc. Oscillations and vibrations have many applications in engineering and science, such as clocks, musical instruments, bridges, buildings, engines, circuits, etc. The features and benefits of Faires' textbook

What is Faires' textbook?


Lagrangian and Hamiltonian mechanics




Lagrangian and Hamiltonian mechanics are two alternative formulations of analytic mechanics that are based on variational principles. They are more general and elegant than Newtonian mechanics, and they can handle systems with constraints, non-Cartesian coordinates, non-conservative forces, etc. more easily. They also provide a bridge between classical and quantum mechanics, as they use similar mathematical tools and concepts.


Lagrangian mechanics is based on the principle of stationary action, which states that the actual path of a system between two fixed points in time is such that the action functional is stationary (i.e., has a minimum, maximum, or saddle point value). The action functional is defined as the integral of the Lagrangian function over time, where the Lagrangian function is the difference between the kinetic and potential energies of the system. The equations of motion for a system are derived from the Euler-Lagrange equation, which is obtained by applying the variational principle to the action functional.


Hamiltonian mechanics is based on the principle of least action, which states that the actual path of a system between two fixed points in phase space is such that the action functional is minimal. The action functional is defined as the integral of the Hamiltonian function over time, where the Hamiltonian function is the sum of the kinetic and potential energies of the system. The equations of motion for a system are derived from Hamilton's equations, which are obtained by applying the variational principle to the action functional.


Lagrangian and Hamiltonian mechanics are equivalent in the sense that they describe the same physical phenomena and give the same results. However, they use different sets of variables and have different advantages and disadvantages. Lagrangian mechanics uses generalized coordinates and velocities, which are convenient for systems with constraints or non-Cartesian coordinates. Hamiltonian mechanics uses generalized coordinates and momenta, which are convenient for systems with symmetries or conserved quantities. Lagrangian mechanics has a direct connection to Newtonian mechanics, while Hamiltonian mechanics has a direct connection to quantum mechanics.
