Mechanical Advantage = 5
Explanation:
The mechanical advantage of a wedge is given by the formula:
MA = L/h
where L is the length of the slope and h is the height.
Here,we have a length of L=10 inches and a height of h=2 inches, so the mechanical advantage is:
MA = L/h
= 10/2
MA = 5
When a machine takes a small input force and increases the magnitude of the output force, a mechanical advantage is produced. When the input force of a machine is 10 pounds and output force is 100 pounds, the mechanical advantage (MA) of 10 is produced which is given below:
MA = Output Force / Input Force
= 100 lbs/10 lbs
= 10
A device that is commonly used to produce mechanical advantage is the automobile jack. The force amount that is applied to the jack handle is multiplied so that a small force can be used to produce a huge force that is needed to lift the automobile.
