Question

As shown, a pipe is anchored to a wall at point A. (Figure 2) During the pipe's installation, several forces are applied to the pipe at different locations. If F1, = 16.61b , F2 = 12 61b , F3= 13.91b , F4 = 18.01b , d1 = 0.400ft, d2 = 0.700ft, and d3 = 0.700ft, what is MRA, the net moment about point A due to these forces'? Assume that moments acting counterclockwise about point A are positive whereas moments acting clockwise are negative. Express your answer numerically In pound-feet to three significant figures.

Explanation / Answer

F1*d1=16.6*.4=6.64 lb.ft
