1. A steel rod with a cross-sectional area of 200 mm² is subjected to
an axial tensile force of 40 kN. What is the normal stress in the
rod?
A. 50 MPa
B. 100 MPa
C. 200 MPa
D. 400 MPa
Answer: B
Stress = Force / Area = 40,000 N / (200 × 10⁻⁶ m²) = 100 MPa.
2. A body initially at rest accelerates uniformly at 2 m/s². How far
does it travel in 5 seconds?
A. 10 m
B. 20 m
C. 25 m
D. 50 m
Answer: C
Distance = ½at² = 0.5 × 2 × 5² = 25 m.
3. What type of stress is produced by a torque acting on a circular
shaft?
A. Normal stress
B. Bearing stress
, C. Shear stress
D. Thermal stress
Answer: C
Torsion in shafts produces shear stress.
4. A system is in static equilibrium when which condition is satisfied?
A. Velocity is constant
B. Acceleration is zero
C. Net force and net moment are zero
D. Kinetic energy is constant
Answer: C
Static equilibrium requires both force and moment equilibrium.
5. Which thermodynamic property is defined as energy per unit
mass?
A. Heat
B. Work
C. Enthalpy
D. Temperature
Answer: C
Enthalpy is a specific (per unit mass) energy property.
6. What is the SI unit of pressure?
A. Joule
B. Pascal
C. Watt
D. Newton
Answer: B
Pressure is measured in Pascals (N/m²).
, 7. A gas undergoes an isothermal expansion. Which property
remains constant?
A. Pressure
B. Volume
C. Temperature
D. Internal energy
Answer: C
Isothermal processes occur at constant temperature.
8. Which law of thermodynamics states that energy cannot be
created or destroyed?
A. Zeroth law
B. First law
C. Second law
D. Third law
Answer: B
The First Law is the law of energy conservation.
9. What is the mechanical advantage of an ideal machine?
A. Less than 1
B. Equal to efficiency
C. Greater than input force/output force
D. Output force/input force
Answer: D
Mechanical advantage is the ratio of output force to input force.
10. Which material property describes resistance to
deformation under load?
A. Ductility
B. Toughness
