Answers Test 2, 2000-2001

Problem 1:
a) x = 1.5, y = 1.5
b)10 rad/s (CCW)
c) 15 slug-ft/s (right)
d) 32.5 slug-ft2/2 (CCW)
e) 17.5 slug-ft2/2 (CCW)
d) 200 ft-lbf

Problem 2:
a) 2.37 rad/s (CW)
b) 4.75 N-m (up)

Problem 3
There should be six velocity terms in the kinetic energy expression so you need at least 5 kinematic equations. Since you will also need to use the velocity of point A yoiu would get a total of about 7 equations.
