## Homework Statement

we did a lab on pulleys. The weight lifted was 19.62 N. It rose 0.20 meter with us applying a lifting force of 11 N and pulling the rose a distance of 0.16.

## The Attempt at a Solution

I tried to find the efficiency of the pulley, so E=work out/work in

so work out=FD=(19.62)(0.20)=3.92

and work in=FD=(11)(0.16)=1.76

yet the work output can't be greater than the work input, so I'm clearly doing something wrong.

Any ideas? Is it a math error or bad lab results? Any help would be great :)
