According to St. Venant’s principle
Notched bar tests are frequently used for testing the
In the creep test, the following type of stress is applied to the specimen
A free bar of length / is uniformly heated from 0°C to a temperature t°C, α is the coefficient of linear expansion and E is the modulus of elasticity. The stress in the bar is
A test specimen is stressed slightly beyond the yield point and then unloaded. Its yield strength
Cupandcone type fracture occurs in the case of
Materials having elongation less than 5% are considered brittle. In such cases, factor of safety is based on
A rod of length 'l’ and crosssectional area ‘A’ rotates about an axis passing through one end of the rod. The extension produced in the rod due to centrifugal forces is (w is the weight of the rod per unit length and ω is the angular velocily of rotation of the rod)
Young’s modulus of elasticity and Poisson’s ratio of a material are 1.25 x 10^{5} MPa and 0.34 respectively. The modulus of rigidity of the material is
In a homogeneous, isotropic elastic material, the modulus of elasticity E in terms of G and K is equal to
