The uniform beam to the right has a mass of 65kg and a total length of 3m. The beam is supported by a pivot point on its far-left end. Determine the upward force, F, needed to balance the beam. This force is located 2.45m from the pivot point.

A diver stands on a diving board with a length of 4.5 m.  The diving board is supported by two pedestals which are 1.5 m apart.  If the diver's weight is 590, determine the force exerted on the left pedestal by the board.  Use positive = up for a sign convention and ignore the weight of the diving board.

A uniform 8.00 m, 1500 kg beam is hinged to a wall and supported by a thin cable attached 2.00 m from the free end of the beam. The beam is fixed to the wall at an angle of 30 degrees above the horizontal. The angle between the cable and the beam is 40 degrees. What are the unknowns? -direction of tension in the cable -direction of the hinge force -magnitude of rhe tension in the cable -magnitude of the hinge force

The uniform 19.0 kg beam below is 6.4 m long and is perfectly balanced about a point 1.4 m from the left end. What is the mass of the block? (Hint: when calculating the torque due to the weight of the beam, consider all of its mass to be located at its center of mass.)
