Question 1

The beam shown below is subjected to a concentrated load of 100 kN at point B and a counterclockwise moment of 40 kN.m at point D. What is the magnitude of the bending moment at point C?

Question 2

A simply supported beam is subjected to a series of concentrated loads. The beam without the loads is shown below.

The shear diagram for segment AB has the following (rectangular) shape.

Describe the shape of the moment diagram for segment AB.

What is the value of the bending moment at point B?

Question 3

The shear diagram for a beam subjected to a uniformly distributed load is shown below.

At what distance from the left end of the beam does the bending moment reach its maximum negative value?

What is the magnitude of the maximum negative moment in the beam?

At what distance from the left end of the beam does the bending moment reach its maximum positive value?

What is the magnitude of the maximum positive moment in the beam?

Question 4

The bending moment in a beam is related to its deflection. Suppose we have a negative bending moment in a beam segment. What does that say about the deflected shape of the segment? (Explain how the beam segment deflects)
