[ Simple machine ] 1. In a machine 500N load is lifted upto 2m by applying an efforts
of 250N. if the effort covers a distance of 8m calculate:
a. MA
b. VR
load
c. Efficiency of a machine[Hint:MA=
effort
effort distance
VR=
Efficiency - Max100]
load distance

2.5 m

Explanation:

Load ( L ) = 500 N

Effort ( E ) = 200 N

Load distance ( LD ) = 3 m

Effort distance ( ED ) = ?

Now, Let's find the Effort distance ( ED )

We know that,

Output work = Input work

i.e L × LD = E × ED

plug the values

multiply the numbers

Swipe the sides of the equation

Divide both sides of the equation by 200

Calculate

Hope this helps..

best regards!!
