Question: Replace the three forces acting on the plate by a wrench ( Figure 1 ) . Suppose that F A = { - 5 6

Replace the three forces acting on the plate by a wrench (Figure 1). Suppose
that FA={-56i}lb,FB={-42j}lb, and FC={28k}lb.
Part A
Determine the magnitude of the resultant force.
Express your answer in pounds to three significant figures.
FR
Correct
Part B
Determine the resultant couple moment.
Express your answer in pound-feet to three significant figures. Enter positive value if MR has the same direction as FR and negative value if MR is opposite to FR.
MR=
lb*ft
