YOUR ANSWER : ?
H V are the algebraic sums of the forces resolved horizontally and vertically respectively, M is the algebraic sum of the moments of forces about any point, for the equilibrium of the body acted upon
YOUR ANSWER : ?
The ratio of maximum shear stress to average shear stress of a circular beam, is
YOUR ANSWER : ?
A steel rod of sectional area 250 sq. mm connects two parallel walls 5 m apart. The nuts at the ends were tightened when the rod was heated to 100°C. If steel = 0.000012/C°, Esteel = 0.2 MN/mm², the tensile force developed at a temperature of 50°C, is
YOUR ANSWER : ?
The ratio of the length and diameter of a simply supported uniform circular beam which experiences maximum bending stress equal to tensile stress due to same load at its mid span, is
YOUR ANSWER : ?
Beams composed of more than one material, rigidly connected together so as to behave as one piece, are known as
YOUR ANSWER : ?
The maximum bending moment for a simply supported beam with a uniformly distributed load w/unit length, is
YOUR ANSWER : ?
Slenderness ratio of a long column, is
YOUR ANSWER : ?
If a solid shaft (diameter 20 cm, length 400 cm, N = 0.8 × 105 N/mm²) when subjected to a twisting moment, produces maximum shear stress of 50 N/mm 2, the angle of twist in radians, is
