Determine the reaction moment at A. Let P = 104 lb, a = 54 in., and EI = 48 × 106 lb·in.2.

Determine the distribution factor DFAB. Let w = 1.8 kip/ft, L1 = 32 ft, and L2 = 23 ft. Assume EI = constant.

Assume that P = 15.8 kips and L = 6.5 ft. Determine the reaction at support A. Assume that EI is constant for the beam.

Determine the fixed end moment FEMCA. Let P1 = 16 kips, P2 = 15 kips, L1 = 21 ft, L2 = 11 ft, and L3 = 16 ft. Assume EI = constant.

The beam supports a single live load of 2,640 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.

Draw the influence line for the shear at B. What is the line’s maximum negative value? Let L1 = 4 m and L2 = 14 m.

Determine the slope at A that would be caused by the distributed load if the fixed support was a pin support, instead. Let w = 7 lb/in., a = 96 in., and EI = 239 × 106 lb·in.2.

Determine the fixed end moment FEMAB with a settlement of 0.8 in. at support B.   As in Chapter 16, include the effect of settlement in the FEM calculation.  Let w = 1.6 kip/ft, L = 20 ft, E = 29,000 ksi and I = 1,600 in.4.

Determine the reaction moment at A. Let w = 5 lb/in., a = 108 in., and EI = 93 × 106 lb·in.2.

Draw the influence line for the shear at B. What is the line’s minimum value? Let L1 = 3 m and L2 = 7 m.
