Q1: What is the primary purpose of the engineering design process?
A. To generate the most complex solution possible
B. To document calculations for legal purposes
C. To systematically solve problems and meet human needs
D. To minimize material costs regardless of performance
Correct Answer: C
Rationale: Correct because the design process is a structured method for identifying
problems and creating effective solutions.
Q2: Convert 5000 milliamperes (mA) to amperes (A).
A. 50 A
B. 0.5 A
C. 5 A
D. 500 A
Correct Answer: C
Rationale: Correct because 1 A = 1000 mA, so 5000 mA / 1000 = 5 A.
Q3: Which of the following is a scalar quantity?
A. Force
B. Velocity
C. Mass
D. Acceleration
Correct Answer: C
Rationale: Correct because mass has magnitude but no direction, defining it as a scalar.
Q4: A 10 kg block is resting on a horizontal surface. What is the normal force acting on the
block? (Assume g = 9.81 m/s²)
A. 10 N
B. 9.81 N
C. 98.1 N
D. 0 N
Correct Answer: C
, 2
Rationale: Correct because normal force equals weight (W = mg), so 10 kg * 9.81 m/s² =
98.1 N.
Q5: Which material property describes a material's ability to return to its original shape after load
removal?
A. Plasticity
B. Ductility
C. Elasticity
D. Hardness
Correct Answer: C
Rationale: Correct because elasticity is the property of a material to recover its original
dimensions upon unloading.
Q6: In a series circuit with three resistors (R1=10Ω, R2=20Ω, R3=30Ω), what is the total
resistance?
A. 15 Ω
B. 60 Ω
C. 60 Ω
D. 5 Ω
Correct Answer: C
Rationale: Correct because in a series circuit, total resistance is the sum of individual
resistances (10+20+30=60).
Q7: What is the SI unit for force?
A. Kilogram
B. Pascal
C. Newton
D. Joule
Correct Answer: C
Rationale: Correct because the Newton (N) is the derived unit for force in the SI system.
Q8: Scenario: A truss bridge is being analyzed. A joint has two members meeting at 90 degrees.
One member is in tension (500 N). The external load is vertical downward (500 N). What is the
force in the second member?
A. 500 N Tension
B. 0 N
C. 500 N Compression
D. 707 N Tension
Correct Answer: C
Rationale: Correct because for static equilibrium in the vertical direction, the vertical
component of the second member must balance the load, implying compression.
