A uniform beam is pivoted at its centre. Two weights are placed on the beam in the positions shown and the beam is balanced by an upward force F.What is the size of F?*1 point

A participant in a “strongman” competition uses an old-fashioned device to move a large load with only muscle power. A 1 ton (910 kg) bucket of rocks is suspended from a sturdy, lightweight beam 0.77 m from a pivot. The man lifts the beam at its end, 3.5 m from the pivot, and holds it steady.  What is the force on the beam from the pivot?

A uniform bridge span weighs 70.0 × 103 N and is 40.0 m long. An automobile weighing 15.0 × 103 N is parked with its center of gravity located 12.0 m from the right pier. What upward support force does the right pier provide?Select one:a.45.5 × 103 Nb.65.0 × 103 Nc.24.5 × 103 Nd.35.5 × 103 N

A uniform rod of length L and weight W is placed on a fulcrum a distance of 0.4L from the left end. On the left end is placed a mass of weight 2W and on the right end a vertical force F is applied to keep the system in balance. What are the magnitude and direction of the force F?

Figure Q9 (a) shows a simply supported beam with forces acting atpoints B and point E.Figure Q9 (a)a) For the beam to be in equilibrium, calculate the support reaction force atpoint C and at point D.

A metre scale has a weight of 10 grams at a distance of 20 cm from the pivot. To balance this a student places another weight at a distance of 35 cm. Calculate the mass of this weight.
