[ 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!!

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
