of https:/ 6789155 Problem 4.13 Determine the moment of each force about C Neglect the thickness of the gate The two boys push on the gate with forces of FA 34 lb and Fa- 55 Ib, as shown. (Figure 1) Figure 1 of 1 Part B 3 fi Counterclockwise Clockwise Br Correct

Solution

Part A: Moment of force F_A about C = 34*(3/5)*9=183.6 lb-ft (clockwise)

Moment of force F_B about C=55*sin60*6 = 285.79 lb-ft(anti clockwise)

Part B:

Since anticlockwise moment is higher than clockwise, the gate will rotate anticlockwise
