We use many simple machines to move heavy loads from one point to another. One of them is inclined plane.
Inclined Plane (for Kids)
An inclined plane is a ramp that assists us in moving heavy objects up and down heights. It is a plane surface set at an angle, other than a right angle, against a horizontal surface.
If Dhakkan in the above video wants to lift and place this barrel on a ledge, it is a bit difficult. With the help of an inclined plane, Dhakkan can now roll the same up a sloping surface, with much lesser effort.
This is because, the force required to raise an object at a distance is greatly reduced by increasing the distance over which the force must be applied.
So the mechanical advantage is the more the distance to be covered, the lesser the force needed to move the load to the raised height.
