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.

Where would you apply a unit load to determine the horizontal deflection at point D?

Support settlements do not cause any stresses in indeterminate structures.

The beam supports a uniform live load of 427 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.

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 C. What is the line’s minimum value? Let L1 = 4 m and L2 = 8 m.
