11.6) A slender bar, 3, with a uniformly distributed mass m is attached at each end to light rollers which move in a smooth fixed guide, 1, shaped as shown in the figure. Assuming gravity acts vertically downward and the bar is released from rest in the configuration shown, what is the angular acceleration of the bar and the force at each roller at the instant the bar is released? For numerical values, use m = 18 kg and r...

Each of the two uniform slender bars OA and BC has a mass of 8
kg. The bars are welded at A to form a T-shaped member and are
rotating freely about a horizontal axis through O. If the bars have
an angular velocity of 4 rad/s CW as OA passes the horizontal
position shown, find the total force R supported by the bearing at
O. Ans: 101.3 N

A uniform slender bar AB of mass m has two light pegs A and B
which are constrained to move in the frictionless circular slot
with center O in the vertical plane. At the position depicted, the
bar is released from rest. Find the bar's initial angular
acceleration when the bar is released in terms of appropriate given
quantities. The pegs each contact only one side of the slot at a
given time.

Question 5 P 0.8 m A rigid uniform square block of mass m = 60 kg is resting on the ground as shown above. A force P is applied to the block at 0.8 m above the ground. The coefficient of kinetic friction between the ground and the block is given by uk = 0.2. It can be shown that the free-body diagram for the situation above is as given below, where F is the friction, N is the normal...
