2- The rectangular plate is made up of 1-ft squares as shown. A 75-1b Force is applied
at point A in the direction shown. Determine the moment of this force about point B and
about point C. Ans. 134.2 lb. ft, 235 lb.ft
3- A force F of magnitude 40N is applied to the gear. Determine the moment of F about
point O Ans. 5.64 N.m
In order to raise the flagpole OC, a light frame OAB is atached to the pole and a
tension of 78O Ib is developed in the hoisting cable by the power winch D. Calculate
the moment Mo of this tension about the hinge point O. Ans. 5010 ib.ft
