Question

| 'The force needed to push a load up an inclined
plain is less than the force needed to lift it directly
Give reasons.
Please answer

Answer 1

Explanation:

Since less effort is needed in lifting a load to a higher level by moving over an inclined plane as compared to that in lifting the load directly, an inclined plane acts as a force multiplier. This is because the mechanical advantage of an inclined plane is always greater than 1.
