Q1.
A simply supported beam with a uniformly distributed load has maximum bending
moment at which location?
A. At the supports B. At midspan
C. At quarter-span points D. At the point of contraflexure
Correct: B - At midspan
Rationale:For a simply supported beam under a uniformly distributed load, the bending
moment diagram is parabolic, with zero moment at the supports and maximum at midspan.
The shear force is zero at midspan, confirming the maximum moment location. Options A, C,
and D are incorrect because the moment is zero at supports, symmetric and decreasing away
from midspan, and there is no contraflexure in this loading case.
Q2.
In a Brayton cycle with regeneration, what is the primary effect of increasing the
regenerator effectiveness?
A. It increases the compressor work B. It decreases the turbine work output.
requirement.
C. It reduces the heat added in the D. It increases the back work ratio.
combustor.
Correct: C - It reduces the heat added in the combustor.
Rationale:A regenerator recovers heat from the turbine exhaust to preheat the air entering
the combustor, thereby reducing the external heat input required. Higher effectiveness means
more heat recovery, lowering fuel consumption. Options A, B, and D are incorrect because
regeneration does not directly affect compressor or turbine work, nor does it increase the
back work ratio.

Q3.
For fully developed laminar flow in a circular pipe, the Darcy friction factor is given by
which expression?
A. f = 64/Re B. f = 0.316/Re^0.25
C. f = 0.184/Re^0.2 D. f = 1.325/[ln(/3.7D)]^2
Correct: A - f = 64/Re
Rationale:The Darcy friction factor for fully developed laminar flow (Re < 2300) is f = 64/Re.
The other options correspond to turbulent flow correlations: B is the Blasius equation, C is the
Prandtl-von Kármán correlation, and D is the Colebrook equation for turbulent flow. These are
not valid for laminar flow.
Q4.
A heat engine operates between 800 K and 300 K. What is the maximum theoretical
efficiency?
A. 37.5% B. 62.5%
C. 75% D. 100%
Correct: B - 62.5%
Rationale:The maximum efficiency is the Carnot efficiency: · = 1 - T_L/T_H = 1 - 300/800 =
0.625 or 62.5%. Options A, C, and D are incorrect because they do not follow the Carnot
relation. A is the ratio T_L/T_H, C is an arbitrary value, and D violates the second law of
thermodynamics.
Q5.
Which dimensionless group represents the ratio of inertial forces to viscous forces?
A. Reynolds number B. Froude number
C. Mach number D. Weber number
Correct: A - Reynolds number
Rationale:The Reynolds number (Re = ÁVD/¼) quantifies the ratio of inertial to viscous forces
and determines flow regime. The Froude number compares inertial to gravitational forces, the
Mach number compares flow speed to speed of sound, and the Weber number compares
inertial to surface tension forces.
