PROBLEM 16.121
End A of the 6-kg uniform rod AB rests on the inclined surface, while end B is
attached to a collar of negligible mass which can slide along the vertical rod
shown. Knowing that the rod is released from rest when = 35° and neglecting the
effect of friction, determine immediately after release (a) the angular acceleration
of the rod, (b) the reaction at B.
25°
Problem 1. End A of the uniform 5-kg bar is pinned freely to the collar, which has an acceleration
a = 4 m/s² along the fixed horizontal shaft. If the bar has a clockwise angular velocity @ = 2 rad/s
as it swings past the vertical, determine the components of the force on the bar at A for this instant.

when t = 6 s.
6. A particle is moving with a velocity of vo when s=0 and t=0. If it is subjected to a
deceleration of a = -kv³ where k is a constant, determine its velocity and position as
functions of time.
7. A particle travels along a straight-line path such that in 4s it moves from an initial position
SA = -8 m to a position SB = +3 m. Then in…
