4. A force of 400 N is exerted 20 cm from the axis rotation. What is the resulting moment of force? a. 80 N b. 80 N-m c. 200 N d. 200 N-m

The system shown has, F,-231 lbf, F,-172 lbf, M-703 ft-lbs, 0-51, a-1.9ft, b-5.3ft, and e- 3.2ft. f. If the force, F,, is moved to point A, what moment needs to be added to create an equivalent system? a A M e b g. If the moment, M, is moved to point A, what moment needs to be added to create an equivalent system? h. If the force, F2, is moved to point A, what moment needs to be added to create an equivalent system? F

A 100-lb vertical force is applied to the end of a lever, which is attached to a shaft at O. Determine a) the moment of the 100-lb force about O; b) the horizontal force applied at A that creates the same moment about O; c) the smallest force applied at A that creates the same moment about O; d) how far from the shaft a 240-lb vertical force must act to create the same moment about O; e) whether any one of the forces obtained in parts b, c, or d is equivalent to the original force. 24 in. 60° 100 lb
