## Hydrostatics Definition and Laws

Hydrostatics Definition
The Branch of science which deals with the study of fluids at rest.
Pascal’s Law
It states that the pressure or intensity of pressure at a point in a fluid at rest is equal in all directions.
Let consider a fluid at rest in a closed container then a change in pressure at one point will be transmitted without loss to every point of the fluid and to the walls of the container.

## Dimensional Analysis and its Application Notes

Dimensional Analysis Definition
All engineering quantities can be defined in four basic or fundamental dimensions- Mass (M), Length (L), Time (T), and Temperature (θ).

## Solid Friction and Viscosity Similarities & Dissimilarities

What is Friction?
Friction is the force that opposes the motion. It acts between the surfaces in contact.
There are basically four types of frictions-
Definition of Solid Friction
The friction that acts between the surfaces of solid surfaces. Static, Sliding and Rolling Frictions are the examples of Solid Frictions.
