A vertical hanging bar of length `l` and mass `m` per unit length carries a load of mass `M` at lower end, its upper end is clamped to a rigid support.The tensile stress a distance `x` from support is (`A``rarr` area of cross - section of bar)

A chain of mass M and length L is held vertical by fixing its upper end to a rigid support. The tension in the chain at a distance y from the rigid support is:

A stationlay unifrom sting of modlulus Y , density rho and length 'I' is hanging from a rigid support. The stress at a distance x from the point of tis suspension.

A rod of length 3 m has its mass per unit length directly proportional to distance x from one of its ends then its centre of gravity from that end will be at

A wire of length L and radius r suspended from rigid support of mass M gm be applied its free end, its elongation is l , then its Young's modulus is

A rod of length 3m and its mass par unit length is directly proportional to the distance x from its one end . The centre of gravity of the rod from that end will be at :-

A thin bar of length L has a mass per unit length lambda , that increases linerarly with distance from one end. If its total mass is M and its mass per unit length at the lighter end is lambda_(0) , then the distance of the centre of mass from the lighter end is

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.

wire of length I has a ear mass density lambda and area of cross-section A and the Young's modulus y is suspended vertically from rigid support. The extension produced in wire due to its own weight

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 bar of mass m and length l is hanging from point A as shown in figure.Find the increase in its length due to its own weight. The young,s modulus of elasicity of the wire is Y and area of cross-section of the wire is A.
