-
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.

-
The elastic section modulus of a rectangular section of width b and depth d about its neutral axis is:
सही उत्तर: क) bd²/6
Z = I / y_max = (bd³/12) / (d/2) = bd²/6.

-
The maximum deflection of a simply supported beam of span L under a uniformly distributed load w per unit length is:
सही उत्तर: घ) 5wL⁴/(384EI)
For a simply supported beam with UDL, δmax = 5wL⁴/384EI at mid-span; wL⁴/384EI is the value for a fixed-fixed beam.

-
The maximum deflection of a simply supported beam of span L with a central point load W is:
सही उत्तर: घ) WL³/(48EI)
Standard result for a simply supported beam with a central point load: δmax = WL³/48EI at mid-span; WL³/3EI is for a cantilever with end load.

-
A cantilever of length L carries a point load P at its free end. The maximum bending moment occurs at the fixed end and equals:
सही उत्तर: घ) PL
The moment at the support is load × lever arm = P × L, the largest value along the cantilever.

-
A material has E = 200 GPa and Poisson's ratio 0.25. What is its modulus of rigidity G?
सही उत्तर: ग) 80 GPa
E = 2G(1 + μ), so G = 200 / (2 × 1.25) = 80 GPa.

-
For structural steel, the value of Poisson's ratio is approximately:
सही उत्तर: ख) 0.30
Poisson's ratio of steel is about 0.25 to 0.30, commonly taken as 0.3; it cannot exceed 0.5 for isotropic materials.

-
Young's modulus of elasticity is defined as the ratio of:
सही उत्तर: ग) Longitudinal stress to longitudinal strain
Within the elastic limit, E = longitudinal (normal) stress / longitudinal strain; shear stress/shear strain is the modulus of rigidity and volumetric ratio is the bulk modulus.

-
Wrist drop following a fracture of the shaft of the humerus is due to injury of the:
सही उत्तर: क) Radial nerve
The radial nerve runs in the spiral groove of the humerus and supplies the wrist extensors.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Fracture of the surgical neck of the humerus is most likely to injure which nerve?
सही उत्तर: घ) Axillary nerve
The axillary nerve winds around the surgical neck with the posterior circumflex humeral artery; injury weakens the deltoid.
