WAN stands for

The elastic limit of an elavator cable is 2xx10^(9)N//m^(2) . The maximum upward acceleration that an elavator of mass 2xx10^(3)kg can have when supported by a cable whose cross sectional area is 10^(-4)m^(2) , provided the stres in cable would not exceed half to the elastic limit would be

The diagram shows the change x in the length of the uniform wire caused by the application of stres F at two different temperatures T and T. The variations shown suggest that

A flat plate of 20 cm squre moves over another similar plate with a thin layer of 0.4 cm of a liquid between them. If a force of one kg. wt. moves one of the plates uniformly with a velocity with a velcoity of 1 ms^(-1) calculate the strain rate, sheraing stres and coefficient of viscosity.

A progressive wave travels on a stretched string. A particle on this string takes 4.0 ms to move from its mean position to one of its extreme positions. The distance between two consecutive points on thew streing which are at their mean positions (at a certain time instant ) is 2.0 cm . Find the frequency , wavelength and speed of the wave.

Iodoform can be obtained on wanning NaOH and iodine with:
