• When a rectangular beam is loaded longitudinally, the shear force develops on the top layer.
• When a body is subjected to a direct tensile stress (σx) in one plane accompanied by a simple shear stress (τxy), the maximum shear stress is
• In a simply supported beam carrying a uniformly distributed load w per unit length, the point of contraflexure
• A riveted joint may fail by
• Which of the following is a proper sequence?
• According to Unwin's formula, the relation between diameter of rivet hole (d) and thickness of plate (t) is given by (where d and t are in mm)
• The bending moment diagram for a simply supported beam loaded in its centre is
• A shear stress across a plane, is always accompanied by a balancing shear stress across the plane and normal to it.
• The total strain energy stored in a body is called proof resilience.
• In the below figure, curve D represents mild steel.
• According to Euler's column theory, the crippling load of a column is given by p = π2 EI/Cl2. In the Euler's formula, the value of C for a column with one end fixed and the other end hinged, is 1/2.
• The moment of resistance of a balanced reinforced concrete beam is based on the stresses in
• The Rankine's constant for a mild steel column with both ends hinged is
• The given figure shows the Mohr's circle of stress for two unequal and like principal stresses (σx and σy) acting at a body across two mutually perpendicular planes. The tangential stress is given by
• Modulus of rigidity may be defined as the ratio of
• The maximum bending moment for the beam shown in the below figure, is
• When a closely-coiled helical spring of mean diameter (D) is subjected to an axial load (W), the stiffness of the spring is given by
• The shear force at the centre of a simply supported beam with a gradually varying load from zero at both ends to w per metre at the centre, is
• The shear force at a certain point on a beam changes sign from +ve value to -ve value or vice versa. The bending moment at that point will be zero.
• The capacity of a strained body for doing work on the removal of the straining force, is called
