At Free End

A spring is stretched by applying a load to its free end. The strain produced in the spring is

Strings Fixed At One End And Free From Other End

A body of mass m is tied to free end of dtring and whiled in a circle about the other end .If the string suddenly breaks , then

A string is hanging from a rigid support. A transverse pulse is excited at its free end. The speed at which the pulse travels a distance x is proportional to

A rigid bar AB is supported in a vertical plane and carries a load Q at its free end. Neglecting the weight of the bar, find the tension of the string CD.

A string is hanging from a rigid support. A transverse pulse is excited at its free end. The speed at which the pulse travels a distance x is proportional to

If a bodyof mass 1000 gm is tied to free end of string of length 100 cm and whirled in a horizontal circle in a second, then the tecsion in the string will be

A massless uniform rod is subjected to froce F at its free end as shown in figure. The ratio of tensile stress at plane P_(1) to stress at P_(2) is
