One end of a uniform rod of mass M and cross-sectional area A is suspended from a rigid support and an equal mass M is suspended from the other end, what is the stress at the mid point of the rod.

A uniform steel rod of cross- sectional area A and L is suspended so that it hangs vertically. The stress at the middle point of the rod is

A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:

One end of a uniform wire of length 'L' and mass 'M' is attached rigidly to a point in the roof and a load of a mass 'm' is suspended from its lower end. If A is the area of cross-section of the wire then the stress in the wire at height 'x' from its lower end (x lt L) is

A uniform rod of mass m and length l is suspended about its end. Time period of small angular oscillations is

One end of a uniform wire of length l and weight W is attached to a point in the roof and a weight W/2 is suspended from the lower end. If A is the area fo cross-section of the wire, then stress of the wire at its midpoint will be

One end of a uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight W_(1) is suspended from its lower end. If S is the area of cross-section of the wire, the stress in the wire at a height 3 L/4 from its lower end is
