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.

“Force times the displacement of its point of application in the direction of the force” is the definition of _______.

Determine the reaction moment at A. Let w = 11 lb/in., a = 126 in., and EI = 54 × 106 lb·in.2.

Determine the deflection at B that would be caused by the distributed load if the middle support was not there. Let w = 8 lb/in., a = 58 in., and EI = 115 × 106 lb·in.2.
