There is a double-pendulum system, each with mass m and length L, attached to a cart of mass M. The cart has linear position x, pendulum 1 has angular position θ, and pendulum 2 has angular position φ. The cart has a force, F, applied in the x-direction to the cart. m,L Using sum of forces, sum of moments, and constraint equations, determine the 12 equations 12 unknowns.

A plane pendulum of length L and mass m is suspended from a block of mass M. The block moves without friction and is constrained to move horizontally only (i.e. along the x axis). You may assume all motion is confined to the xy plane. At t = 0, both masses are at rest, the block is at , and the pendulum has angular deflection with respect to the y axis. a) Using and as generalized coordinates, find the Lagrangian...
A pendulum consists of a mass m suspended from a string of length L. When the pendulum is swinging, how much greater is the mass’s potential energy when the string is displaced from the vertical by the angle θ than when the mass is at the lowest position?
Q4 A ring of mass M and radius R is attached so that it can pivot asone of a rod of mass M and length 2R. the system is suspended by a pin at the other end of the rod and all in a uniform gravitational field,g; thus forming a double pendulum.

(a) Consider a pendulum with a mass m suspended at the end of a light string of length l. As it moves through the air the mass experiences a damping force that is proportional to its speed, with constant of proportionality y.

A simple pendulum consists of a ball of mass M hanging from a uniform string of mass m and length L, with m << M. (a) If the period of oscillations for the pendulum is T, derive an expression for the speed of a transverse wave in the string when the pendulum hangs at rest in terms of m, M, T and g (the acceleration due to gravity). Your expression should not include L. (b) If the string is made...
