1. The hoop stress in a riveted cylindrical shell of diameter (d), thickness (t) and subjected to an internal pressure (p) is (where ? = Efficiency of the riveted joint)
3. If there is a fall in the temperature of a composite body, then a member having greater coefficient of linear expansion will be subjected to compressive stress.
4. A column of length (l) with both ends fixed may be considered as equivalent to a column of length __________ with one end fixed and the other end free.
5. The actual neutral axis of a reinforced cement concrete beam is based on the principle that the moment of areas of compression and tension zones at the neutral axis are equal.
6. According to Euler's column theory, the crippling load of a column is given by p = ?2EI/Cl2. In the Euler's formula, the value of C for a column with both ends fixed is 4.
7. When a closely-coiied helical spring of mean diameter (D) is subjected to an axial load (W), the deflection of the spring (?) 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)
8. If percentage elongation of a certain specimen made of a material 'A' under tensile test is 30% and the percentage elongation of a specimen with same dimensions made of another material 'B' is 40%, then material 'B' is more ductile than material 'A'.
