Question 1

A statically determinate beam and an influence line are shown below.

Which of the following statements is true?

Question 2

Consider the statically determinate beam and the influence line shown below.

Which of the following statements is true?

Question 3

Consider the beam and diagrams shown below.

Which diagram represents the influence line for bending moment at C?

Question 4

Consider the following statically determinate beam with two internal hinges. Suppose we wish to draw the reaction influence line for the support at C. To do so, we need to give the beam a vertical unit displacement at C. Assuming that the beam has been moved up by a unit distance at C, please answer the following questions.

What happens to joint B when C moves up a unit?

What happens to joint D when C moves up a unit?

What happens to segment AB when joint C moves up a unit?

What happens to segment BD when joint C moves up a unit?

What happens to segment DE when joint C moves up a unit?
