An effort of 50 Newton applied at one end of a Lever raises a load of 1000 Newton at the other end a.what is the mechanical advantage of the lever b.what is the velocity ratio c.load by 1 cm how far must the effort move
Asked by Samrat | 30 Jun, 2018, 09:04: PM
answered-by-expert Expert Answer
Mechanical advantage = Load/Effort = 1000 / 50 = 20
 
velocity ratio is same as Mechanical advantage for ideal condition (efficiecy = 100%)
 
To raise the load by 1 cm , effort has to move 20 cm.
