The cantilever beam is built into a wall at O. Neglecting the weight of the beam, determine the support reactions at O.
Neglecting the weights of the members, determine the magnitude of the pin reaction at D when the frame is loaded by the 200-N ·m couple.
Compute the magnitudes of all forces acting on member CDE of the frame.
Calculate all forces acting on member CDB.
The load in the bucket of a skid steer loader is 600 lb with its center of gravity at G. For the position shown, determine the forces in the hydraulic cylinders AC and DE.
The tool shown is used to crimp terminals onto electric wires. The wire and terminal are inserted into the space D and are squeezed together by the motion of slider A. Compute the magnitude of the crimping force.
The 50-N force is applied to the handle of the toggle cutter. Determine the force exerted by the cutting blade CB on the workpiece E.
The pins at the end of the retaining-ring spreader fit into holes in a retaining ring. When the handgrip is squeezed, the pins spread the retaining ring, allowing its insertion or removal. Determine the spreading force P caused by the 8-lb forces applied to the handgrip.
