-
A point of contraflexure in a beam is a point where:
सही उत्तर: क) The bending moment changes sign
Points of contraflexure occur where the bending moment passes through zero and changes sign, i.e., curvature reverses.

-
A propped cantilever (fixed at one end, simply supported at the other) under vertical loads is statically indeterminate to what degree?
सही उत्तर: घ) 1
Under vertical loads there are three unknowns (vertical reaction and moment at fixed end, vertical reaction at prop) and two equations, so it is indeterminate to degree 1.

-
What is the degree of static indeterminacy of a fixed-fixed (encastre) beam under general planar loading?
सही उत्तर: ग) 3
There are six reaction components (3 at each fixed end) and three equilibrium equations, so the degree of indeterminacy is 6 − 3 = 3.

Hooke's law holds good for a material up to the:
सही उत्तर: ख) Limit of proportionality
Stress is directly proportional to strain only up to the limit of proportionality.

-
The polar moment of inertia of a solid circular shaft of diameter d is:
सही उत्तर: ग) πd⁴/32
J = πd⁴/32, which is twice the diametral moment of inertia πd⁴/64.

-
In a beam of solid circular cross-section, the maximum shear stress is how many times the average shear stress?
सही उत्तर: ख) 4/3
For a solid circular section, τmax = (4/3) × V/A, occurring at the neutral axis.

-
In a beam of rectangular cross-section, the maximum shear stress is how many times the average shear stress?
सही उत्तर: क) 1.5
Shear stress distribution in a rectangle is parabolic with τmax = 1.5 × V/(bd) at the neutral axis.

-
For a column with one end fixed and the other end free, the theoretical effective length is:
सही उत्तर: क) 2L
A fixed-free column buckles like half of a pin-ended column of length 2L, so Le = 2L.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
For a column with both ends fixed, the effective length used in Euler's formula (theoretical) is:
सही उत्तर: ग) L/2
Theoretical effective lengths: both ends hinged L, both fixed L/2, one fixed one hinged L/√2, one fixed one free 2L.

-
The second moment of area of a rectangle of width b and depth d about its centroidal axis parallel to the width is:
सही उत्तर: घ) bd³/12
About the centroidal axis parallel to b, I = bd³/12; bd³/3 is about the base.
