Review Problems for the Final Exam – Set 1 (bonus for submission)
1. Determine the tension T in the cable and the reactions at A
and B for the cases (a) h=0.75d and (b) h=1.25d. The object
of mass m is homogeneous and the feet are small. Friction is
negligible (Caution: Ensure that equilibrium is possible in
each case).
Solution:
