- A material is said to be perfectly elastic if
- Pick up the correct statement from the following:
- For calculating the allowable stress of long columns σ0 = σy/n [1 - a (1/r)²]is the empirical formula, known as
- The ratio of maximum and average shear stresses on a rectangular section, is
- A simply supported beam which carries a uniformly distributed load has two equal overhangs. To have maximum B.M. produced in the beam least possible, the ratio of the length of the overhang to the total length of the beam, is
- section modulus of a square section of side B and that of a circular section of the ratio of the diameter D, is
- A simply supported uniform rectangular bar breadth b, depth d and length L carries an isolated load W at its mid-span. The same bar experiences an extension e under same tensile load. The ratio of the maximum deflection to the elongation, is
- The equivalent length is of a column of length having both the ends fixed, is
