1. The ends of a uniform bar AB with length l= 36.0 in and weight W = 30.0 lb are attached to collars of negligible weight that slide without friction along fixed bars. A vertical force P is applied to collar B. The bar is initially at rest in the position shown and the initial angular acceleration of A is 40.0 ft/s to the left, aA = – 40 ft/s i. o= 30° {= 36 in O Draw a free...

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.

1. A uniform horizontal bar of length L = 2.0 m and weight 144 N is pinned to a vertical wall and supported by a thin wire that makes an angle of 0 = 150 with the horizontal. A mass M, with a weight of 302 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 573 N. What is the maximum possible distance from the wall at which mass M can be placed...

A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform
density is placed upon a horizontal, frictionless surface. A small
rubber puck (mass 250 g) slides towards the bar with a speed (2
m/s) directed perpendicular to the bar. It collides perfectly
elastically with the bar at a distance (d) from the center of mass
of the bar in such a way that the puck rebounds with a velocity (1
m/s).
