A pressure vessel is said to be a thin shell when the ratio of wall thickness of the vessel to its diameter is __________ 1/10.
-
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.
-
A tensile test is performed on a mild steel round bar. Its diameter after fracture will

Two closely coiled helical springs 'A' and 'B' are equal in all respects but the diameter of wire of spring 'A' is double that of spring 'B' The stiffness of spring 'B' will be __________ that of spring 'A'
-
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
-
When a body is subjected to a direct tensile stress (σx) in one plane accompanied by a simple shear stress (τxy ), the maximum normal stress is
-
The strain energy stored in a body, when suddenly loaded, is __________ the strain energy stored when same load is applied gradually.
-
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 proof resilience per unit volume of a material is known as modulus of resilience.
-
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)
