A beam which is fixed at one end and free at the other is called
-
When a body is subjected to three mutually perpendicular stresses, of equal intensity, the ratio of direct stress to the corresponding volumetric strain is known as
-
The bending moment at a section tends to bend or deflect the beam and the internal stresses resist its bending. The resistance offered by the internal stresses, to the bending, is called
-
The section modulus of a rectangular section about an axis through its C.G., is
-
The ratio of shear modulus to the modulus of elasticity for a Poisson's ratio of 0.4 will be
-
A closely coiled helical spring is of mean diameter (D) and spring wire diameter (d). The spring index is the ratio of
-
The strain energy stored in a body, when the load is gradually applied, is (where σ = Stress in the material of the body, V = Volume of the body, and E = Modulus of elasticity of the material)
-
If the diameter of pressure vessel is 15 times the wall thickness, the vessel is said to be a thick shell.
