Question 1

Which law states that the pressure at any point in a static fluid depends only on the depth of that point?

Accepted Answer

Pascal's law

Answer

Pascal's law states pressure applied to an enclosed fluid is transmitted equally in all directions, and static pressure depends only on fluid depth (P = ρgh).

Question 2

In a simply supported beam with a central point load P and span L, the maximum bending moment is:

Accepted Answer

PL/4

Answer

For a simply supported beam with central point load, maximum bending moment occurs at midspan: M_max = PL/4.

Question 3

What does the Laplace transform of a unit impulse function δ(t) equal?

Accepted Answer

1

Answer

The Laplace transform of the Dirac delta function δ(t) is 1, making it useful as a test input in control system analysis.

Question 4

Which heat transfer mode does NOT require a medium for energy transmission?

Accepted Answer

Radiation

Answer

Radiation transfers energy via electromagnetic waves and can propagate through a vacuum, unlike conduction and convection which require matter.

Question 5

In a DC circuit, three resistors of 6 Ω, 3 Ω, and 2 Ω are connected in parallel. What is the equivalent resistance?

Accepted Answer

1 Ω

Answer

1/R_eq = 1/6 + 1/3 + 1/2 = 1/6 + 2/6 + 3/6 = 6/6 = 1, so R_eq = 1 Ω.
