Q. For a simply supported beam with a point load at one end, what is the reaction force at the opposite end?

Solution

The reaction force at the opposite end of a simply supported beam with a point load at one end is equal to the load W.

Correct Answer: A — W

Q. What is the maximum bending moment in a simply supported beam with a central point load?

Solution

The maximum bending moment for a simply supported beam with a central point load is given by M = WL^2/8.

Correct Answer: A — WL^2/8

Q. What is the relationship between the stiffness of a beam and its deflection?

Solution

The stiffness of a beam is inversely proportional to its deflection; as stiffness increases, deflection decreases.

Correct Answer: B — Inversely proportional

Q. What is the shear force at the support of a simply supported beam with a uniform load?

Solution

The shear force at the support of a simply supported beam with a uniform load is WL/2.

Correct Answer: A — WL/2
