Draw the influence line for the moment at B. What is the line’s maximum value? Let L1 = 5 m and L2 = 8 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.

The beam supports a single live load of 3,000 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.

Draw the influence line for the shear at B. What is the line’s maximum value? Let L1 = 5 m and L2 = 8 m.

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

Using the method of consistent deformations, determine the magnitude of the reaction at A. Let w = 18 kN/m and L = 9 m.

Determine the magnitude of the largest shear force in the beam. Assume L = 3 ft, P = 750 lb, and w = 300 lb/ft.

We can only use Castigliano’s Second Theorem to calculate the deflections of trusses and beams. It does not work for frames.

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

According to the textbook, temperature changes do not cause any stresses in indeterminate structures.
