Problems The beam shown supports a load that varies uniformly from 100 N/m at the left end to 200 N/m at the right end. The lengths of the beam segments are d1 = 12 m, d2 = 8 m, and d3 = 4 m. 1. Determine the reaction at A. 2. Determine the reaction at C. 3. Draw a schematic of the standard convention for the meaning of positive shears and bending moments (see Section 8.2).

Bending Moment

In general, we can define the bending moment as the reaction induced when a certain amount of load or force is applied to an element which makes it bend.
