Question

give reason of mechanical advantage is greater then one in second class lever

Answer 1

Answer:

As the ratio of effort (force) arm length to load arm length increases, the mechanical advantage of a second class lever increases. In a wheelbarrow, the closer the load is to the wheel, the greater the mechanical advantage. Nutcrackers are also an example of a second class lever.

Step-by-step explanation:

It is highly helpful to know that the mechanical advantage 1.(M.A.) of Class two levers is usually greater than one. It is because the overall length of the Effort Arm is higher than the overall length of Load Arm. It is easily known by MA is effort arm/load arm
