(25 points) anchored to two facing walls as shown in the figure. Inside the cart, a pendulum of mass m (not included in the mass M of the cart) and length l is hung from the ceiling, z is the dis...
Prob. 7.3: A simple pendulum (mass M and length L) is suspended from a cart (mass m) that canoscillate on the end of a spring of spring constant k, as shown in the figure at right. (a) Write the Lagrangian in terms of the generalized coordinates x and ?, where x is the extension of the spring from its equilibrium length and ? is the angle of the pendulum from the vertical. Find the two Lagrange equations. (b) Simplify the...
A pendulum consists of a string of length L and a mass m hung at one end and the mass oscillates along a circular arc. Part a) Familiarize yourself with the derivation of omega = Squareroot g/L to hold. i) Explain succinctly how the angular frequency of oscillation omega = Squareroot g/L comes about from Newton's Law, where g is the gravitational acceleration. ii) One assumption required is the small angle approximation: sin theta = theta and cos theta =...
