Determine the moment reaction at A 1 800 ftlb 1 600 ftlb 1 4

Determine the moment reaction at A. 1, 800 ft-lb 1, 600 ft-lb 1, 400 ft-lb 2, 200 ft-lb 1, 100 ft-lb

Solution

taking Moment at A,

here Force of 200 lb is zero , because it is acting on line of action of A,

Taking clockwise positive and anti-clockwise negative,

Ma=300*6+800-200*5

Ma=1600 ft-lb.....................Answer is b
