Chapter 5, Problem 68P

The 180-lb homogeneous bar is supported by a ball-and-socket joint at A and two cables attached to B. Determine the forces in the cables.

The homogeneous 240-lb bar is supported by a rough horizontal surface at A, a smooth vertical surface at B, and the cable BC. Draw the FBD of the bar and count the unknowns.

Compute the magnitudes of the reactions at pin A and the roller at D. Neglect the weight of the body.

The 350-lb homogeneous plate has the shape of an isosceles triangle. The plate is supported by a thrust hinge at A, a slider hinge at B, and the cable CD. Find the force in the cable and the magnitudes of the hinge reactions.

Compute the magnitude of the pin reaction at B. Neglect the weights of the structural members.

The hinge shown is the type used on the doors of some automobiles. If a torsion spring at F applies the constant couple C0=20lbft to member ABF, calculate the force P required to hold the door open in the position shown.
