I have worked out all relevant information (i hope) but im unsure of how to work out the law of the machine from it. We've done a test and recorded our results of a Pully.(adsbygoogle = window.adsbygoogle || []).push({});

We had to measure different loads and see what effort was required for each load. What is the formula for working out the law of the machine?

I have worked out Mechanical Advantage (MA), Velocity Ratio (VR) and the efficiency (η).

Any help be great
