Law of Machines

Describe briefly all the Law of Machines?

E

Expert

Verified

Machines that are employed to lift a load are governed by the ‘Law of machines’ that states that the effort to be exerted on the machine (p) is associated to the weight (w) that it can lift as:

p = mw + c

Here m and c are the positive constants that are the features of machine.
