The length of a steel wire is 1 meter and radius is 10 mm. The force on it is 1xx10^(5) Newton according to its length...

Two wires of diameter 0.25 cm , one made of steel and other made of brass, are loaded as shown in the figure. The unloaded length of the steel wire is 1.5 m and that of brass is 1.0 m . Young's modulus of steel is 2.0 xx 10^(11) Pa and that of brass is 1.0 xx 10^(11) Pa. Compute the ratio of elongations of steel and brass wires. (/_\l_("steel"))/(/_\l_("brass"))=?

The breaking force of wire is 10^(4) N and radius is 1xx10^(-3) m. If the radius is 2xx10^(-3) m, then the breaking force will be

Two wires of diameter 0.25 cm, one made of steel and the other made of brass are loaded as shown in figure. The unloaded length of steel wire is 1.5 m and that of brass wire is 1.0 m. Compute the elongations of the steel and the brass wires .Young's modulus of steel is 2.0 xx 10^(11) Pa and that of brass is 9.1 xx 10^(11) Pa.

The figure shows two creates that are connected by a steel wire that passes over a pulley. The unstretched length of the wire is 1.5 m, and its cross - sectional area is 1.3xx10^(-5)m^(2) . The pulley is frictionless and massless. When the crates are accelerating, determine the change in length of the wire. Ignore the mass of the wire.

The length of a steel wire is l_(1) when the stretching force is T_(1) and l_(2) when the stretching force is T_(2) . The natural length of the wire is

In the fig the two parallel wires PQ and ST are at 30 cm apart. The currents flowing in the wires are according to fig. The force acting over a length of 5m of the wires is- (1) 5xx10^(-4) N (2) attraction (3) 5xx10^(-8) N (4) repulsion

The length of a steel wire increases by 0*5cm , when it is loaded with a weight of 5*0kg . Calculate force constant of the wire and workdown in stretching the wire. Take g=10ms^(-1) .

Increase in length of a wire is 1 mm when suspended by a weight. If the same weight is suspended on a wire of double its length and double its radius, the increase in length will be

When the resistance of copper wire is 0.1 Omega and the radius is 1mm, then the length of the wire is (specific resistance of copper is 3.14 xx 10^(-8) ohm xx m )

A load is suspended from a steel wire with a radius of 1mm. The load extends the wire the same amount as does heating by 20^(@)C . Find the load (approx). alpha_("steel") = 1.1 xx 10^(-5) K^(-1) , Young's modulus = 21.6 xx 10^(10) N//m^(2)
