Question

a. What is mechanical advantage? What is its value for class one and class two levers?
answer it pls ​

Answer 1

Answer:

The mechanical advantage of a first class lever depends upon the placement of the fulcrum. If the fulcrum is closer to the load than to the input force, the lever has a MA > 1. If the fulcrum is exactly in the middle of the load and the input force, the MA = 1. If the fulcrum is closer to the input force than to the load, the lever's MA < 1.

Answer 2

Answer:

Explanation:

1. The theoretical mechanical advantage of a system is the ratio of the force that performs the useful work to the force applied, assuming there is no friction in the system. In practice, the actual mechanical advantage will be less than the theoretical value by an amount determined by the amount of friction.
2. What is a Class 1 levers?

What is its value for class one and class two levers?  In a Class One Lever, the Fulcrum is located between the Load and the Force. The closer the Load is to the Fulcrum, the easier it is to lift (increased mechanical advantage). Examples include see-saws, crow bars, hammer claws, scissors, pliers, and boat oars. ... The force or effort is the end or handle of the scissors.
