When a rectangular beam is loaded transversely, the maximum tensile stress is developed on the
27.
The compressive strength of brittle materials is __________ its tensile strength.
28.
When a closely-coiied helical spring of mean diameter (D) is subjected to an axial load (W), the deflection of the spring (δ) is given by (where d = Diameter of spring wire, n = No. of turns of the spring, and C = Modulus of rigidity for the spring material)
29.
In spring balances, the spring is used
30.
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 both ends fixed is 4.
