3.) 15.40 – Collar B moves up at constant velocity vB = 1.5 m/s. Rod AB has length = 1.2 m. The incline is
at angle = 25°. Compute an expression for the angular velocity of rod AB, ė and the velocity of end A of the
rod (✓✓) as a function of v₂,1,0,0. Then compute numerical answers for ȧ & y_ with 0 = 50°.
2.) 15.12 The assembly shown consists of the straight rod ABC which passes through and is welded to the
grectangular plate DEFH. The assembly rotates about the axis AC with a constant angular velocity of 9 rad/s.
Knowing that the motion when viewed from C is counterclockwise, determine the velocity and acceleration of
corner F.
