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.

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

An influence line represents the variation of either the reaction, shear, moment, or deflection at a specific point in a member due to a _______ load.

The slope-deflection equations relate the _______ at the ends of a member to the rotations and displacements of its ends and the external loads applied to the member.

Determine the beam slope at B. Let w = 2.3 kip/ft, L1 = 37 ft, and L2 = 21 ft. Assume EI = constant.

Using the method of consistent deformations, determine the magnitude of the reaction at A. Let w = 22 kN/m and L = 7 m.

Determine the reaction moment at A. Let w = 4 lb/in., a = 144 in., and EI = 76 × 106 lb·in.2.
