Question

Express the relation for the mechanical advantage for lever in terms of load, effort and its arms when the lever is in balanced position​

Answer 1

Answer:

An inclined plane is like a Ramp, which makes it possible to move a heavy load to a new height using less force (but over a longer distance).  

In the above figure a inclined plane is shown with height h and length l.  

The mechanical advantage of a inclined plane or a ramp can be found using this formula:

M. A.=  

vertical height

length

​

 

M. A.=  

h

l
