Problem #2) The thin plate ABCD has mass 10kg and is held stationary in the position shown (p= 30°) by a wire BH and the two massless parallel links AF and DE. At t = 0sec, the wire is cut and the plate is released from rest; it immediately moves in a pure translation motion due to the system's geometric constraint by the links. Find the forces in each link immediately after the wire is cut. All dimensions are in millimeters. 150 A D -500 H B IC T 200

A cylinder, a sphere and a hoop of the same masses and radii are rolling from an inclined plane. Which object arrives first at the bottom of the incline? (I_cylinder- 1/2 mR^2 and I hoop = mR^2, 1_sphere 2/5 mR^2) A heavy boy and a lightweight girl are balanced on a massless seesaw. If they both move forward so that they are one-half their original distance from the pivot point, what will happen to the seesaw? Assume that both people are small enough compared to the length of the seesaw to be thought of as point masses.
