Pro f .J .P .How Prof. J. Deyst Handout #4 March 6, 2003 Due: March 13, 2003 16.61 Homework Assignment #4 1. Consider the spring pendulum analyzed before. The arm attached to the rotating shaft has length d =0 . 8m, as shown in the figure. The shaft is rotating with a constant angular velocity Ω = 0 . 4 rad/sec, but the pendulum is free to change length ( L )and swing ( θ ). Given that the spring constant is k and the mass of point P is m , find the equations of motion for this system. Note that gravity acts. Pay special attention to Frame selection and FARM. 2. A pendulum of mass m and length l is in a uniform gravitational field. The support point is moving in the vertical direction with a displacement d ( t ), which is a known function of time (Both ˙ d ( t )and ¨ d ( t
