1. The SI unit of force is the
A. joule
B. newton
C. watt
D. pascal
Rationale: The SI unit of force is the newton, defined as kg·m/s².
2. A beam loaded in pure bending experiences
A. torsion
B. moment
C. shear
D. compression
Rationale: Pure bending refers to bending moment without shear.
3. The derivative of sin(x) is
A. cos(x)
B. -sin(x)
C. cos(x)
D. -cos(x)
Rationale: The derivative of sin(x) with respect to x is cos(x).
,4. For a closed system, energy can be exchanged by
A. mass flow
B. magnetic work
C. chemical reactions
D. heat and work
Rationale: Closed systems exchange energy as heat or work, not mass.
5. The stress concentration factor is highest for
A. square hole
B. sharp corner
C. circular hole
D. smooth fillet
Rationale: Sharp corners cause high stress concentration.
6. The Laplace transform of 1 is
A. 1
B. 1/s
C. s
D. eˢ
Rationale: L{1} = 1/s for s > 0.
7. Resistivity is inversely proportional to
A. resistance
B. area
C. conductivity
D. length
Rationale: Conductivity is inverse of resistivity.
8. Bernoulli’s equation assumes
A. viscous flow
B. unsteady flow
C. compressible flow
D. inviscid flow
Rationale: Bernoulli’s applies to inviscid, steady, incompressible flow.
, 9. The natural frequency of a spring-mass system increases by
A. increasing mass
B. decreasing mass
C. decreasing stiffness
D. adding damping
Rationale: Lower mass increases natural frequency.
10.The pH of a neutral solution at 25°C is
A. 7.5
B. 7
C. 6.5
D. 14
Rationale: Neutral pH at 25°C is 7.
11.A rigid body has
A. variable shape
B. deformable material
C. constant distance between particles
D. no mass
Rationale: Rigid body assumption means distances remain fixed.
12.The Fourier series represents periodic functions using
A. exponentials only
B. sines and cosines
C. polynomials
D. hyperbolic functions
Rationale: Fourier series uses sines/cosines to represent periodic signals.
13.Ideal gas law is expressed as
A. PV = n
B. PV = nRT
C. P/T = nR
D. V/T = nR
Rationale: PV = nRT is the ideal gas equation.
