Strength of Materials Questions

• When a body is subjected to two equal and opposite forces, acting tangentially across the resisting section, as a result of which the body tends to shear off across the section, the stress and strain induced is

• Transverse fillet welds are designed for
• The equivalent length, of a given column with given end conditions, is the length of an equivalent column of the same material and cross-section with hinged ends, and having the value of crippling load equal to that of the given column.
• The maximum shear stress in a thin spherical shell subjected to an internal pressure (p) is zero.
• The relation between equivalent length (L) and actual length (l) of a column for both ends fixed is
• Poisson's ratio is the ratio of linear stein to the volumetric strain.

• The lower layer of the beam as shown in the below figure, will be
• A square beam and a circular beam have the same length, same allowable stress and the same bending moment. The ratio of weights of the square beam to the circular beam is
• The perpendicular distance between the centre lines of the successive rows, is called pitch.
• The values of equivalent length (L) and actual length (l) of a column for both ends hinged is the same
• When a body is subjected to a direct tensile stress (σ) in one plane, then tangential or shear stress on an oblique section of the body inclined at an angle θ to the normal of the section is
• The neutral axis of a transverse section of a beam passes through the centre of gravity of the section and is
• The distance between the centre of a rivet hole to the nearest edge of plate, is called
• The change in length due to a tensile or compressive force acting on a body is given by (where P = Tensile or compressive force acting on the body, l = Original length of the body, A = Cross-sectional area of the body, and E = Young's modulus for the material of the body)
