Two identical uniform slender rods with length 2.2 m and mass 3 kg are pin-connected at A. One of the rods is also pin-connected at its other end to fixed point O. If the system is released from rest in the position shown in the figure, find the initial acceleration of point B at the end of the rightmost rod. The angle is 21°. For the purposes of reporting the acceleration, consider + to the right and +y upward.

A system of machines shown has a motor which has a radius of 1 inch that begins rotating at w=41 (1-e^-t) rad/s, where t is in seconds. The smooth pulley 4 inches in radius and the blades (16 inches radius) has the same center of rotation and mass. Assuming no frictional force is developed throughout the system, calculate the normal acceleration of point P in inches/seconds^2 at time t=0.5sec.
