Question 4

For the composite beam of problem 3, check all the statements below that are true.

Answer a. At the interface between the steel and the brass the strain in the steel will be higher than the strain in the brass.

b. At the interface between the steel and the brass the strain in the steel will be lower than the strain in the brass.
c. At the interface between the steel and the brass the strain in the steel will be the same as the strain in the brass.
d. At the interface between the steel and the brass the stress in the steel will be higher than the stress in the brass.
e. At the interface between the steel and the brass the stress in the steel will be lower than the stress in the brass.
f. At the interface between the steel and the brass the stress in the steel will be the same as the stress in the brass.
g. The transformed moment of inertia for the beam will be higher if steel is used as the reference material than if brass is used as the reference material.

h. The transformed moment of inertia for the beam will be lower if steel is used as the reference material than if brass is used as the reference material.
i. The transformed moment of inertia for the beam will be the same regardless of which material is used as the reference material.
j. The centroid location will be higher (closer to the top) if steel is used as the reference material than if brass is used as the reference material.

k. The centroid location will be lower (closer to the bottom) if steel is used as the reference material than if brass is used as the reference material.
l. The centroid location will be the same regardless of which material is used as the reference material.
