Step 1
The moment of a force is given by the formula: Moment = Force x Perpendicular distance For the 100N force, the perpendicular distance is 2m. So the moment of the 100N force about point O is: Moment1 = 100N x 2m = 200Nm For the 300N force, the perpendicular Show more…

The direction cosines of the force F are cos ̘_x = 0.818, cos ̘_y = 0.182, and cos ̘_z = -0.545. The support of the beam at O will fail if the magnitude of the moment of F about O exceeds 100 kN-m. Determine the magnitude of the largest force F that can safely be applied to the beam.

Determine the resultant couple moment acting on the beam. Solve the problem two ways: (a) Sum moments about point O; and (b) Sum moments about point A. Units Used: kN = 10^3 N Given: F1 = 2 kN, θ1 = 30 deg F2 = 8 kN, θ2 = 45 deg a = 0.3 m b = 1.5 m c = 1.8 m
