A great majority of structures being built today are statically determinate.

Assume that P = 10.2 kips and L = 6.5 ft. Determine the reaction at support A. Assume that EI is constant for the beam.

The truss is pin supported at A and rocker supported at E. Assume all members are pin connected. Determine the magnitude of the force in member CD. Let F1 = 500 lb, F2 = 650 lb, and L = 5 ft.

The beam supports a single live load of 1,790 lb, a uniform live load of 350 lb/ft, a uniform dead load of 85 lb/ft. Determine the maximum positive shear that can be developed at point B. Assume the support at A is a pin and C is a roller. The influence lines for VB and MB are shown, along with the peak values of the influence lines.

Draw the influence line for the shear at B. What is the line’s maximum positive value? Let L1 = 3 m and L2 = 10 m.

Determine the reaction force at B. Let w = 17 lb/in., a = 49 in., and EI = 100 × 106 lb·in.2.

The beam supports a single live load of 2,130 lb. Determine the maximum negative shear that can be developed at point B. Assume the support at A is a pin and C is a roller. The influence lines for VB and MB are shown, along with the peak values of the influence lines.

Draw the influence line for the moment at B. What is the line’s minimum value? Let L1 = 5 m and L2 = 8 m.

Assume that P = 7.4 kips and L = 7.5 ft. Determine the reaction at support A. Assume that EI is constant for the beam.

The beam is fixed at wall B. Determine the vertical reaction force By at point B. Let L = 30 ft, M = 1,100 lb·ft, P = 775 lb and w0 = 225 lb/ft.
