Question

the two forces f1 and f2 acting at A have a resultant force of Fr= -100lb. determine the magnitude and coordinate direction angles of f2

Answer 1

To determine the magnitude and coordinate direction angles of f2, subtract the given magnitudes of f1 from the resultant force.

Step-by-step explanation:

To determine the magnitude and coordinate direction angles of f2, we need to consider the resultant force, Fr -100lb, and the component forces f1. Let's assume that f1 has magnitudes of f1x=10.0lb, f1y=-20.4lb, and f1z=2.0lb. Since the total force is the sum of the individual forces, we can subtract f1 from Fr to find f2 as follows:

f2 = Fr - f1

f2 = -100lb - (10.0lb + -20.4lb + 2.0lb)

f2 = -100lb - -8.4lb

f2 = -91.6lb

Therefore, the magnitude of f2 is 91.6lb.

Since we were only given the magnitudes for f1 and f2, we cannot determine the coordinate direction angles without additional information.

Answer 2

Two forces F1 and F2 act on the screw eye. The resultant force FR has a magnitude of 125 lb and the coordinate direction angles shown in (Figure 1) . Determine the magnitude of F2. Determine the coordinate direction angle α2 of F2. Determine the coordinate direction angle β2 of F2. Determine the coordinate direction angle γ2 of F2.
