Determine the reaction force at B. Let w = 15 lb/in., a = 48 in., and EI = 38 × 106 lb·in.2.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member BF. What is the line’s maximum value? Let L = 18 ft.

Using the method of consistent deformations, determine the force in member AD. Let P = 14 kN, L1 = 3 m, and L2 = 6 m. Assume EA = constant.

On this quiz, “maximum” refers to the highest vertical point on the influence graph and “minimum” refers to the lowest vertical point on the graph.Draw the influence line for the vertical reaction at A. What is the line’s maximum value? Let L1 = 3 m and L2 = 11 m.

The beam supports a uniform live load of 334 lb/ft. 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.

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