The property of a body by virtue of which it tends to regain its original configuration as soon as the deforming forces applied on the body are removed is called elasticity. Coefficient of elasticity, E = (stress)/("strain") = (F//a)/(Delta l//l) = (F l)/(pi r^2(Delta l)) The value of E depends upon nature of material. A material with higher value of E is said to be more elastic. Read the above passage and answer the following question : (i) Which is more elastic steel or rubber ? Why ?

The delay in recovery on removal of the deforming force is called ___

Name the property of an object by virtue of which it opposes or tends to oppose any change in its state.

Viscosity is the property of fluid by virtue of which fluid offers resistance to deformation under the influence of a tangential force. In the given figure as the the plate moves the fluid particle at the surface moves from position 1 to 2 and so on, but particles at the bottom boundry remain stationary. if the gap between palte and bottom boundary is small, fluid particles in between plate and bottom moves with velocities as shown by linear velocity distribution curve otherwise the velocity distribution may be parabolic. As per Newton's law of viscity the tangential force is related to time rate of deformation - (F)/(A) alpha (d' theta)/(dt) but y = (d' theta)/(dt) = u, (d' theta)/(dt) = (u)/(y) then F = eta A(u)/(y), eta = coefficient of viscosity for non-linear velocity distribution - F = eta A(du)/(dy) where (u)/(y) or (du)/(dy) is known as velocity gradiant. The velocity gradient just below the plate, in above problem is equal to - (per second)
