Amusement Park Physics -- Carousel - Learner

Amusement Park Physics -- Carousel. Pendulum. Pendulum rides are a little like the swing sets you might remember from your childhood. Swings give you a feeling of flying in a controlled manner. You pump your legs to provide enough force to increase the height of the swing's arc, and enjoy the increased velocity of the downward swing.

17–62. The pendulum consists of a 30-lb sphere and a O B

Two men exert constant vertical forces of 40 lb and 30 lb at ends A and B of a uniform plank which has a weight of 50 lb. If the plank is originally at rest in the horizontal position, determine the initial acceleration of its center and its angular acceleration. Assume the plank to be a slender rod. 15 ft A B 40 lb 30 lb

Acceleration and rotation in a pendulum ride, …

For a pure pendulum ride only the "vertical" axis would show non- zero results. The "vertical" component of the accelerometer (i.e. the component along the co-moving z-axis in figure 2) depends on the angleθand on the maximum angular displacement,θ 0. At the turning point, the vertical component will begcosθ

Vertical Spring Forced Pendulum (Lagrange equations)

Given a spring constant, k, and the assumption of a massless spring, I formulated the potential energy of the system to be: U = (1/2)ky^2+mg (y-l*cos (θ)) where l is the length of the pendulum, and I have chosen the potential to be zero at y = 0 & θ = pi/2. The kinetic energy of the system should be that given only by the mass of the pendulum.
