Question

Study the given lever and calculate the effort to the balance the load used in it ?
​

Answer 1

explanation is in the attachment

hope it is helpful to you

Answer 2

solution given:

load distance [l.d.]=2m-1.5m=0.5m

effort distance [e.d.]=1.5m

load [l]=500N

effort[E]=?

we have

load ×load distance =effort ×effort distance

500N×0.5=effort ×1.5

effort =250/1.5=166.67N

so

effort =166.67N
