1. 

Gear A is in mesh with gear B as shown. If A starts from rest and has a constant angular acceleration of A = 2 rad/s2, determine the tome needed for B to attain an angular velocity of B = 50 rad/s.

A. t = 62.5 s
B. t = 250.0 s
C. t = 10.00 s
D. t = 40.0 s

2. 

The 2-m-long bar is confined to move in the horizontal and vertical slots A and B. If the velocity of the slider block at A is 6 m/s, determine the bar's angular velocity and the velocity of block B at the instant = 60°.

A. AB = 3.46 rad/s , vB = 3.46 m/s 9
B. AB = 3.00 rad/s , vB = 3.00 m/s 9
C. AB = 3.00 rad/s , vB = 6.00 m/s 9
D. AB = 6.00 rad/s , vB = 10.39 m/s 9

3. 

Determine the angular acceleration of link BC at the instant = 90° if the collar C has an instantaneous velocity of vc = 4 ft/s and deceleration of ac = 3 ft/s2 as shown.

A. BC = 36.2 rad/s2
B. BC = 36.2 rad/s2
C. BC = 27.8 rad/s2
D. BC = 27.8 rad/s2

4. 

During a gust of wind, the blades of the windmill are given an angular acceleration of = (0.2 ) rad/s2, where is measured in radians. If initially the blades have an angular velocity of 5 rad/s, determine the speed of point P located at the tip of one of the blades just after the blade has turned two revolutions.

A. vP = 5.60 ft/s
B. vP = 19.87 ft/s
C. vP = 14.05 ft/s
D. vP = 18.81 ft/s

5. 

The pulley os pin-connected to block B at A. As cord CF unwinds from the inner hub with the motion shown, cord DE unwinds from the outer rim. Determine the angular acceleration of the pulley at the instant shown.

A. = 80.0 rad/s2
B. = 160.0 rad/s2
C. = 180.0 rad/s2
D. = 53.3 rad/s2
