The articulated crane boom has a weight of 125 lb and the force acting at the pin A and the force in the hydrauliccylinder BC when the boom is in the position shown.

The airstroke actuator at D is used to apply a force of F = 200 N on the member at B. Determine the horizontal and vertical components of reactionat the pin A and the force of the smooth shaft at C on the member.

The airstroke actuator at D is used to apply a force of F on the member at B. The normal reaction of the smooth shaftat C on the member is 300 N. Determine the magnitude of F and the horizontal and vertical components of reaction at pin A.

The 300-lb electrical transformer with center of gravity at G issupported by a pin at A and a smooth pad at B. Determine the horizontal and vertical components of reaction at the pin A and the reaction of the pad B on the transformer.

A skeletal diagram of ahand holding a load is shown in the upper figure. If the load and the forearm have masses of 2 kg and 1.2 kg, respectively, and their centers of mass are located at G1 and G2, determine the forcedeveloped in the biceps CD and the horizontal and vertical components of reaction at the elbow joint B. The forearm supporting system can be modeled as the structural system shown inthe lower figure.

As an airplane’s brakes are applied, the nose wheel exerts two forces on the end of the landing gear as shown. Determine the horizontal and vertical components ofreaction at the pin C and the force in strut AB.

The 1.4-Mg drainpipe is held in the tines of the fork lift. Determine the normal forces at A and B as functions of the blade angle u and plot theresults of force (vertical axis) versus u (horizontal axis) for 0 … u … 90°.

If the force of F = 100 lb is applied to the handle of the bar bender, determine the horizontal and vertical...
