Question 3

Logarithmic decrement of a damped single degree of freedom system is ξ. If stiffness of spring is doubled and mass is made half, then logarithmic decrement of the new system will be equal to

Question 4

Two beams of equal cross sectional area are subjected to equal bending moment. If one beam has square section and the other has circular section then,

Question 5

A piping system consists of three pipes arranged in series, the lengths of the pipes are 1200 m, 750 m and 600 m and diameters 750 mm, 600 mm, 450 mm respectively. Transform the system to an equivalent 450 mm diameter pipe __________.

Question 6
