According to the textbook, temperature changes do not cause any stresses in indeterminate structures.

Draw the influence line for the shear at B. What is the line’s maximum positive value? Let L1 = 5 m and L2 = 13 m.

Draw the influence line for the moment at B. What is the line’s minimum value? Let L1 = 3 m and L2 = 13 m.

The beam supports a single live load of 1,740 lb. 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.

Determine the beam deflection at point H. Assume that EI = 4.49 × 1010 kN-mm2 is constant.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member BC. The line’s maximum value occurs _______. Let L = 14 ft.

Determine the slope at A that would be caused by the concentrated force if the fixed support was a pin support, instead. Let P = 172 lb, a = 50 in., and EI = 76 × 106 lb·in.2.

Assume that P = 7.6 kips and L = 8.0 ft. Determine the reaction at support A. Assume that EI is constant for the beam.

Draw the influence line for the moment at B. What is the line’s maximum value? Let L1 = 4 m and L2 = 15 m.

Using the method of consistent deformations, determine the magnitude of the reaction at C. Let w = 27 kN/m and L = 8 m.
