Question

An effort of 500N was applied to lift a stone of 1000N with a crowbar. Calculate the mechanical advantage.

​

Answer 1

simple machine aage se steep hoti hai

to hamari force kam lagti hai par weight easily uthaya jata hai and for 2nd direction should be perpendicular as in perpendicular hamara work hota hai f×s.cos 90

Explanation:

Answer 2

`{ \tt{mechanical \: advantage = (load)/(effort) }} \\ \\ \dashrightarrow \: { \tt{m.a = (1000)/(500) = (10)/(5) }} \\ \\ { \boxed{ \tt{mechanical \: advantage = 2}}}`
