Q. What is the relationship between the stiffness (k) of a beam and its moment of inertia (I)?

A. k ∝ I
B. k ∝ 1/I
C. k ∝ I^2
D. k ∝ √I

Solution

The stiffness (k) of a beam is directly proportional to its moment of inertia (I), meaning k ∝ I.

Correct Answer: A — k ∝ I

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

A. Directly proportional
B. Inversely proportional
C. No relationship
D. Exponential

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 a section located at a distance 'x' from the left end of a simply supported beam with a point load at the center?

A. W/2
B. W/4
C. 0
D. W-x

Solution

The shear force (V) at a section located at a distance 'x' from the left end of a simply supported beam with a point load (W) at the center is V = W/2 - x.

Correct Answer: D — W-x

Q. What is the shear force at a section of a simply supported beam just to the left of a point load?

A. 0
B. P
C. P/2
D. P - V

Solution

The shear force (V) just to the left of a point load (P) on a simply supported beam is equal to V = P.

Correct Answer: B — P

Q. What is the shear force at the midpoint of a simply supported beam subjected to a point load of 10 kN at one end?

A. 0 kN
B. 5 kN
C. 10 kN
D. 15 kN

Solution

Shear Force at midpoint = 10 kN (load at one end) - 0 kN (no load on the other end) = 10 kN.

Correct Answer: A — 0 kN

Q. What is the shear force at the midpoint of a simply supported beam with a point load at one end?

A. W/2
B. W
C. 0
D. W/4

Solution

The shear force at the midpoint of a simply supported beam with a point load at one end is 0, as the load is not applied at that point.

Correct Answer: C — 0

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

A. Zero
B. WL
C. WL/2
D. WL/4

Solution

The shear force at the fixed support of a cantilever beam with a uniform load (w) is equal to the total load, which is WL.

Correct Answer: B — WL

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

A. P
B. 0
C. P/2
D. P/4

Solution

The shear force (V) at the support of a simply supported beam with a point load (P) at one end is equal to P.
