Correct Answer Logic:
A propped cantilever has reactions: fixed end provides vertical reaction, horizontal reaction, and moment (3 unknowns); simple support provides vertical reaction (1 unknown) — total 4 unknowns. Available equilibrium equations: 3 (\(\sum F_x = 0\), \(\sum F_y = 0\), \(\sum M = 0\)). Degree of static indeterminacy \(= 4 - 3 = 1\). One compatibility equation (typically zero deflection at the prop) is needed to solve it.

Boilers Mechanical Engineering QUESTION #2471
Question 2825
In the Lewis beam strength equation for gear tooth bending, the allowable bending load \(F_b\) is expressed as:
  • \(F_b = \sigma_b B / P_d\)
  • \(F_b = \sigma_0 B p Y = \sigma_0 B \pi Y / P_d\)✔️
  • \(F_b = \sigma_0 B C / P_d^2\)
  • \(F_b = \pi \sigma_0 B d / N\)
Correct Answer Logic:
The Lewis equation: \(F_b = \sigma_0 B p Y\) where \(\sigma_0\) is allowable bending stress, \(B\) is face width, \(p=\pi/P_d\) is circular pitch, and \(Y\) is the Lewis form factor.

Dairy Food Science and Technology QUESTION #5873
Question 2827
Which best explains why homogenized milk does not form a cream layer?
  • Fat globules are chemically altered
  • Fat globule size is reduced below \(2\;\mu\text{m}\) preventing creaming by Stokes' law✔️
  • Density of fat is increased to match skim milk
  • Casein micelles coat fat globules preventing coalescence
Correct Answer Logic:
Homogenization reduces fat globule diameter to below \(2\;\mu\text{m}\). By Stokes' law, creaming velocity \(v \propto r^2\); smaller globules rise negligibly slowly, preventing cream layer formation.

Civil / Architecture QUESTION #2358
Question 2834
The concept of embodied energy in sustainable building materials refers to:
  • The energy stored in a building's thermal mass that regulates indoor temperature
  • The total energy consumed in all processes associated with production, transportation, and installation of a building material throughout its life cycle✔️
  • The energy saved by using renewable energy systems integrated into the building
  • The operational energy required to maintain HVAC systems in a building
Correct Answer Logic:
Embodied energy is the total energy input (in MJ/kg or GJ/tonne) consumed across all processes to produce, transport, and install a building material — including raw material extraction, manufacturing, and on-site installation. It is distinguished from operational energy (energy used during building occupancy). High embodied energy materials (e.g., aluminium, steel) have significant upfront carbon footprints even in energy-efficient buildings.

General Abilities QUESTION #7990
Question 2836
A number is increased by 20% and then decreased by 20%. The final value of the number:
  • Does not change
  • Decreases by 2%
  • Increases by 4%
  • Decreases by 4%✔️
Correct Answer Logic:
Let the number be 100.
After 20% increase: \(100 \times 1.20 = 120\)
After 20% decrease: \(120 \times 0.80 = 96\)
Net change: \(96 - 100 = -4\), i.e., a decrease of 4%.

Mathematics QUESTION #1327
Question 2837
The exact value of \(\int_1^3\dfrac{1}{x^2}\,dx\) is:
  • \(\dfrac{1}{3}\)
  • \(\dfrac{2}{3}\)✔️
  • \(\dfrac{1}{9}\)
  • \(\dfrac{4}{3}\)
Correct Answer Logic:
\(\int_1^3\dfrac{1}{x^2}\,dx=\left[-\dfrac{1}{x}\right]_1^3=-\dfrac{1}{3}+1=\dfrac{2}{3}\). This is the exact value; the Trapezoidal Rule approximation approaches this as the step size decreases.

Journalism / Mass Communication QUESTION #6416
Question 2840
The concept of intra-personal communication describes communication that occurs within a single individual. Which of the following is the BEST example of intra-personal communication?
  • A telephone conversation between two friends
  • A newspaper editorial addressed to the general public
  • A person's internal process of thinking, meditating, or reasoning — where all communication elements (source, message, channel, receiver) exist within the same individual✔️
  • A group discussion in a classroom
Correct Answer Logic:

The textbook classifies human communication into two broad types:

  • Intra-personal communication: “The part of communication in which self of a human being is involved only and the communication is confined to one human entity. This means that all the elements which come into action in a given piece of communication are located within the self of an individual. A message originating from source part of the brain travels through the channel of nerves to reach another location, however close it may be to the point of origin.” Examples: thinking, reasoning, meditation, monologue, and dreaming.
  • Inter-personal communication: Involves two or more individuals, and is further classified into interpersonal (one-to-one), group communication, organisational communication, and mass communication.

The key distinguishing criterion is that in intra-personal communication, all elements — source, encoder, channel, decoder, and receiver — exist within the same person. No external communication partner is required.
