Q. In a beam subjected to bending, what is the relationship between the bending moment and the curvature?
A.
M = EI * ρ
B.
M = ρ / EI
C.
M = E * I * ρ
D.
M = ρ / E
Show solution
Solution
The relationship between the bending moment (M) and the curvature (ρ) in a beam is given by M = EI * ρ, where E is the modulus of elasticity and I is the moment of inertia.
Correct Answer:
A
— M = EI * ρ

Q. What is the effect of increasing the length of a beam on its deflection under a constant load?
A.
Deflection increases
B.
Deflection decreases
C.
Deflection remains the same
D.
Deflection doubles
Show solution
Solution
Increasing the length of a beam under a constant load will increase its deflection, as deflection is proportional to the cube of the length (L^3).
Correct Answer:
A
— Deflection increases
