Question: User: A 40 cm horizontal beam is acted on by five forces. The forces are applied at 10 cm intervals along the beam, as shown in the diagram.
Force 1: 10 N downward at 0 cm
Force 2: 20 N directed downward and to the right at 30° below the horizontal at 10 cm
Force 3: 50 N upward at 20 cm
Force 4: 20 N directed upward and to the right at 65° above the horizontal at 30 cm
Force 5: 10 N directed downward and to the right at 45° below the horizontal at 40 cm
Assume the beam is 40 cm long and the forces are applied at the positions shown.
Questions:
Calculate the moment (torque) produced by each force about the pivot at 0 cm.
Determine the net torque about the 0 cm pivot.
State whether the net torque is clockwise or counterclockwise.
Repeat the calculation using the pivot at 10 cm, 20 cm, 30 cm, and 40 cm.
For each pivot, determine the net force acting on the beam.
Which pivot produces the greatest clockwise or counterclockwise moment?
