Draw the influence line for the vertical reaction at A. What is the line’s minimum value? Let L1 = 6 m and L2 = 4 m.

Using the method of consistent deformations, determine the force in member AD. Let P = 11 kN, L1 = 5 m, and L2 = 3 m. Assume EA = constant.

Determine the slope at A that would be caused by the concentrated force if the fixed support was a pin support, instead. Let P = 234 lb, a = 65 in., and EI = 126 × 106 lb·in.2.

Using the method of consistent deformations, determine the magnitude of the reaction at B. Let w = 18 kN/m and L = 7 m.

Assume that P = 16.6 kips and L = 5.0 ft. Determine the reaction at support A. Assume that EI is constant for the beam.

Determine the reaction force at B. Let w = 19 lb/in., a = 70 in., and EI = 35 × 106 lb·in.2.

Draw the influence line for the moment at B. What is the line’s minimum value? Let L1 = 8 m and L2 = 4 m.

The beam supports a single live load of 2,500 lb. Determine the maximum positive moment 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.

Using the method of consistent deformations, determine the force in member AD. Let P = 17 kN, L1 = 6 m, and L2 = 3 m. Assume EA = constant.

According to the textbook, temperature changes cause stresses in indeterminate structures.
