A mass of 5 kg is hung from a copper wire of 5 mm diameter and 2 m in length. Calculate the extension produced. What should be the minimum diameter of the wire so that its elastic limit is not exceeded ? Elastic limit for copper `=1.5xx10^(9)` dyne `cm^(-2)` and Y for copper `=1.1xx10^(12)` dyne `cm^(-2)`

A mass of 4kg is hung from a metal wire of radius 0.5 mm and length 3m. Find the extension produced in the wire. What should be minimum radius of the wire so that the elastic limit of 20 xx 10^7 N/m^2 of the metal wire is not exceeded ? Y=20x10^10N/m^2.

Explain the formation os stationary waves by analytical method. Show the formation of stationary wave diagramatically. A mass of 1 kg is hung from a steel wire of radius 0.5 mm and length 4 m. Calculate the extension produced. What should be the area of cross-section of the wire so that elastic limit is not exceeded? Change in radius is negligible ? Given g=9.8m//s^(2) , Elastic limit of steel is 2.4xx10^(8)N//m^(2) , Y for steel (Y_("steel"))=20xx10^(10)N//m^(2),pi=3.142 ).

An object of mass 5 kg is suspended by a copper wire of length 2 m and diameter 5 mm. Calculate the increase in the length of the wire. In order not to exceed the elastic limit, what should be the minimum diameter of the wire ? For copper, elastic limit =1.5 xx 10 ^(9) "dyne" //cm ^(2) , (Y) = 1.1 xx 10 ^(12) "dyne"//cm^(2).
