B M Sharma Solutions for Chapter: Properties of Matter, Exercise 1: DPP 5.1

A steel ring of radius r and cross-section area $A$ is fitted on to a wooden disc of radius $R \left(R>r\right)$. If Young's modulus be $E$, then the force with which the steel ring is expanded is

A uniform cube is subjected to volume compression. If each side is decreased by $1\%,$ then bulk strain is

The pressure applied from all directions on a cube is $P$. How much its temperature should be raised to maintain the original volume? The volume elasticity of the cube is $\beta$ and the coefficient of volume expansion is$a$

Mark the wrong statement

A student plots a graph from his readings on the determination of Young's modulus of a metal wire but forgets to write the labels (as shown in the figure). The quantities on  $X$a nd $Y$ axis may be respectively

Which of the following statements are correct?

The stress-strain graphs for two materials are shown in the figure (assume the same scale)

A copper and a steel wire of the same diameter are connected end to end. A deforming force $F$ is applied to this composite wire, which causes a total elongation of $1 \mathrm{cm}$. The two wires will have,
