If $$\delta$$ is the depression produced in beam of length $$L$$, breath $$b$$ and thickness $$d$$, when a load is placed at the mid point, then

The normal density of mercury is $$p$$ and its bulk modulus is $$B$$. The increase in density of gold when a pressure $$p$$ is applied uniformly on all sides is:

A uniform pressure p is exerted on all sides of a solid cube at temperature $${t^0}C$$. By what amount should the temperature of the cube be raised in order to bring its volume back to the value it had before the pressure was applied? The coefficient of volume expansion of the cube y and the bulk modulus is B.

A thick rope of rubber of density $$1.5 \times {10^3}{\text{kg/}}{{\text{m}}^{\text{3}}}$$ and Young's modulus $$5 \times {10^6}{\text{N/}}{{\text{m}}^2}$$ , $$8 m$$ length is hung from the ceiling of a room , the increases in its length due to its own weight is :

 $$\left( {g = 10{\text{m/}}{{\text{s}}^{\text{2}}}} \right)$$

A force $$F$$ is applied along a rod of transverse sectional area $$A$$. The normal stress to a sectior $$PQ$$ inclined $$\theta$$ to transverse section will be maximum for $$\theta$$ (in degree) is 

Assume that a block of very low shear modulus is fixed on an inclined place as shown. Due to elastic forces it will deform. What will be the shape of the block?

A steel wire of length $$1.5\ m$$ and area of cross section $$1.5\ mm^{2}$$ is stretched by $$1.5\ cm$$. then the work done per unit volume. $$(Y =2\times 10^{11}Nm^{2})$$.

A horizontal rod is supported at both ends and loaded at the middle. It L and Y are length and Young's modulus respectively, then depression at the middle is directly proportional to

A-3 Two wire of equal length and cross-sectional area suspended as shown in figure. Their Young's modulus are $$ Y_1 and Y_2 $$ respectively. The equivelent Young's modulus will be 

If a rubber ball is taken down to a 100 m deep lake, its volume decreases by 0.1%. If $$g=10\quad m/{ s }^{ 2 }$$ then the bulk modulus of elasticity for rubber, in N/$${ m }^{ 2 }$$, is
