A truck is pulling a car out of a ditch by means fo a steel cable that is ${\displaystyle 9.1m}$ long and has a radius of ${\displaystyle 5mm}$. When the car just beings to move, the tension in the cable is ${\displaystyle 800N}$. If Young's modulus for steel is ${\displaystyle 2\times {10}^{11}N/m^2}$ then the strecth in the cable is (neraly)

A tow truck is pulling a car out of a ditch by means of steel cable that is 9.1 m long and has a radius of 0.50 cm. When the car just begins to move, the tension in the cable is 890 N. How much has the cable stretched ?

Young 's modulus of steel is $2.0\times {10}^{11}Nm/\left(2\right)$. Express it is $\frac{\text{dyne}}{c}{m}^2$.

The Young's modulus of steel is $1.9\times {10}^{11}N{m}^{-2}$ . Calculate its value in dyne $c{m}^{-2}$.

A steel wire of length 5 m and area of cross-section $4m{m}^2$ is stretched by 2 mm by the application of a force. If young's modulus of steel is $2\times {10}^{11}N/m^2,$ then the energy stored in the wire is

What is the work done per unit volume when a steel wire is stretched by $0.2\%$ of its original length ? (Young's modulus of steel is $2\times {10}^{11}N/m^2$)

How much will a 30 m steel tape 1 cm wide and 0.05 cm thick stretch under a pull of force of 300 N , if Young's modulus of steel is $2\times {10}^{11}N{m}^{-2}$?

Calculate the velocity of sound in steel given Young's modulus of steel $=2\times {10}^{11}N{m}^{-2}$ and density of steel $=7800kg{m}^{-3}$.

The area of a cross-section of steel wire is $0.5c{m}^{-2}$ and Young's modulus of steel is $2\times {10}^{11}N{m}^{-2}$. The force required to stretch by 0.5% of its length is

A steel rod has a radius 10 mm and a length of 1.0 m. A force stretches it along its length and produces a strain of $0.32\%$. Young's modulus of the steel is $2.0\times {10}^{11N{m}^{-2}}$. What is the magnitude of the force stretching the rod?

(a) A wire $4m$ long and 0.3 mm, calculate the potential energy stored in the wire.
Young's modulus for the material of wire is $2.0\times {10}^{11}N/m^2$.
