1. A force of 50 N acts at 30° to the horizontal. What is its horizontal
component?
A. 25 N
B. 35 N
C. 43.3 N
D. 50 N
Answer: C
Rationale: Fx=Fcos30∘=50×0.866=43.3NF_x = F \cos 30^\circ = 50
× 0.866 = 43.3 NFx=Fcos30∘=50×0.866=43.3N
2. A simply supported beam carries a central point load. Maximum
bending moment occurs at:
A. Supports
B. Midspan
C. Quarter span
D. Free end
Answer: B
Rationale: Maximum moment occurs at midspan for symmetric loading.
,3. Newton’s second law is:
A. F=maF = maF=ma
B. F=mvF = mvF=mv
C. F=m/aF = m/aF=m/a
D. F=a/mF = a/mF=a/m
Answer: A
4. A body in equilibrium must have:
A. Zero velocity
B. Zero acceleration
C. Zero force only
D. Constant momentum
Answer: B
5. Work done by constant force is:
A. F/tF/tF/t
B. FdcosθFd \cos \thetaFdcosθ
C. mamama
D. mv2mv^2mv2
Answer: B
6. Angular velocity unit is:
A. rad/s
B. m/s
, C. N·m
D. kg/s
Answer: A
7. Centroid of a rectangle lies at:
A. Corner
B. Midpoint of diagonal
C. Center
D. Edge
Answer: C
8. Moment of inertia increases when:
A. Mass decreases
B. Mass is closer to axis
C. Mass is farther from axis
D. Velocity increases
Answer: C
9. Kinetic energy formula:
A. mvmvmv
B. 1/2mv21/2 mv^21/2mv2
C. mghmghmgh
D. FdFdFd
Answer: B
