1. A projectile is launched at 30 m/s at an angle of 40° above the
horizontal. Neglecting air resistance and using g = 9.81 m/s², what is
the approximate time of flight?
A. 2.5 s
B. 3.9 s
C. 3.9 s
D. 5.2 s
The time of flight depends on the vertical velocity component and is
calculated using 2v₀sinθ/g, which yields approximately 3.9 seconds.
2. A simply supported beam carries a central point load. Where is the
maximum bending moment located?
A. At the supports
B. At the left quarter span
C. At the right quarter span
D. At midspan
For a centrally loaded simply supported beam, the maximum bending
moment occurs directly under the load at midspan due to symmetry.
, 3. A 10 Ω resistor and a 20 Ω resistor are connected in parallel. What is
the equivalent resistance?
A. 30 Ω
B. 15 Ω
C. 6.67 Ω
D. 5 Ω
Parallel resistance is found using the reciprocal sum, giving an equivalent
resistance of approximately 6.67 ohms.
4. The slope of the shear force diagram corresponds to which quantity?
A. Load intensity
B. Bending moment
C. Axial force
D. Deflection
The derivative of shear force with respect to position equals the distributed
load intensity on the beam.
5. A steel rod experiences axial stress of 200 MPa and strain of 0.001.
What is the modulus of elasticity?
A. 100 GPa
B. 150 GPa
C. 200 GPa
D. 250 GPa
Young’s modulus is stress divided by strain, resulting in 200 GPa for the
given values.
6. Which thermodynamic process occurs at constant pressure?
A. Isothermal
B. Isochoric
C. Adiabatic
D. Isobaric
, An isobaric process maintains constant pressure while allowing volume and
temperature to change.
7. A fluid flows through a pipe that narrows in diameter. According to
continuity, velocity will:
A. Decrease
B. Remain constant
C. Increase
D. Become zero
Continuity requires mass flow rate conservation, so velocity increases as
cross-sectional area decreases.
8. What is the primary function of a diode in an electrical circuit?
A. Amplification
B. Resistance control
C. Allow current in one direction only
D. Energy storage
A diode permits current flow in one direction while blocking reverse flow.
9. The determinant of a matrix is zero. What does this imply?
A. The matrix is diagonal
B. The matrix is orthogonal
C. The matrix is singular and not invertible
D. The matrix has positive eigenvalues only
A zero determinant indicates linear dependence among rows or columns,
making the matrix non-invertible.
10. What is the unit of angular momentum in SI?
A. kg·m/s
B. N·m
C. kg·m²/s
