A car accelerates uniformly from rest to 60 mph in 10 seconds. What
is its acceleration in ft/s²? (1 mph = 1.467 ft/s)
A. 6.0 ft/s²
B. 8.8 ft/s²
C. 9.8 ft/s²
D. 14.7 ft/s²
B. 8.8 ft/s² (CORRECT ANSWER)
Rationale: Convert 60 mph to ft/s: 60 × 1.467 = 88.02 ft/s.
Acceleration = Δv/Δt = 88.02/10 = 8.80 ft/s².
A car accelerates uniformly from rest to 60 mph in 10 s. Acceleration
in ft/s²? (1 mph = 1.467 ft/s)
A. 6.0
B. 8.8
C. 9.8
D. 14.7
,B. 8.8 ft/s² (CORRECT ANSWER)
Rationale: 60 mph × 1.467 = 88.02 ft/s; a = 88.02/10 = 8.80 ft/s².
∫(3x² + 2x) dx from 1 to 3 =
A. 20
B. 28
C. 34
D. 36
C. 34 (CORRECT ANSWER)
Rationale: ∫(3x²+2x)dx = x³ + x²; at 3: 27+9=36; at 1: 1+1=2;
36−2=34.
The probability of a shaft failing the test is 0.02. If 5 shafts are tested
independently, what is the probability that exactly one fails?
A. 0.02
B. 0.092
C. 0.090
D. 0.10
B. 0.092 (CORRECT ANSWER)
Rationale: Binomial: P(X=1) = C(5,1)(0.02)¹(0.98)⁴ =
5×0.02×0.922368 = 0.09224.
A force F = 10i + 20j – 5k N. Its magnitude (N) is closest to:
A. 22.9
,B. 25.0
C. 27.4
D. 30.0
A. 22.9 (CORRECT ANSWER)
Rationale: |F| = √(10²+20²+(-5)²) = √(100+400+25) = √525 ≈ 22.91
N.
A 5 kg block slides down a frictionless 30° incline. The acceleration
(m/s²) along the incline is:
A. 4.9
B. 8.5
C. 9.8
D. 2.5
A. 4.9 (CORRECT ANSWER)
Rationale: a = g sinθ = 9.81 × sin30° = 9.81 × 0.5 = 4.905 m/s².
A steel rod (E = 200 GPa) of length 2 m and cross-sectional area 100
mm² is stretched by 0.5 mm. The axial force (N) is:
A. 5000
B. 10000
C. 20000
D. 50000
A. 5000 (CORRECT ANSWER)
, Rationale: σ = E ε = E (ΔL/L) = 200e9 Pa × (0.5e-3/2) = 50e6 Pa.
Force = σA = 50e6 × 100e-6 = 5000 N.
In a tensile test, the 0.2% offset yield strength is determined from a
stress-strain curve by:
A. Drawing a line parallel to the linear portion offset by 0.2% strain
B. Finding the maximum stress
C. Drawing a line from origin with slope 0.2% of E
D. The stress at 0.002 strain
A. Drawing a line parallel to the linear portion offset by 0.2%
strain (CORRECT ANSWER)
Rationale: The 0.2% offset method uses a line parallel to the elastic
modulus line, offset by 0.002 strain.
Water flows through a pipe with diameter 0.1 m at 2 m/s. The
Reynolds number (kinematic viscosity ν = 1e-6 m²/s) is:
A. 1e5
B. 2e5
C. 2e4
D. 5e4
B. 2e5 (CORRECT ANSWER)
Rationale: Re = VD/ν = 2 × 0.e-6 = 0.2/1e-6 = 200,000 =
2×10⁵.
