Question

A force of $100\mathrm{N}$ is applied on a nail of area $0.001\mathrm{sq}.\mathrm{cm}$. What is the thrust?

Answer 1

1. Thrust: It is the total force exerted by a body perpendicular to the surface.
2. It is given that a force of $100\mathrm{N}$ is exerted on a nail of area $0.001\mathrm{sq}.\mathrm{cm}$.
3. By definition of thrust, the thrust on the surface due to the nail is equal to the force exerted by the nail, that is $100\mathrm{N}$

Hence, the thrust is $100\mathrm{N}$
