Q. What is the effect of increasing the length of a beam on its deflection under a uniform load?
-
A.
Increases deflection
-
B.
Decreases deflection
-
C.
No effect
-
D.
Depends on material
Solution
Increasing the length of a beam under a uniform load increases its deflection, as deflection is proportional to the length cubed.
Correct Answer:
A
— Increases deflection

Q. What is the relationship between the moment of inertia (I) and the deflection of a beam?
-
A.
Directly proportional
-
B.
Inversely proportional
-
C.
No relationship
-
D.
Exponential relationship
Solution
The deflection of a beam is inversely proportional to the moment of inertia (I); as I increases, deflection decreases.
Correct Answer:
B
— Inversely proportional
