The law of the machine is (where P = Effort applied to lift the load, m = A constant which is equal to the slope of the line, W = Load lifted, and C = Another constant which represents the machine friction.)
The law of machine can be defined as the relation between the load lifted (W) and the effort applied (P).
The law of machine is given by relation P = mW + C
Where,
P = Effort applied
W = Load lifted
m = A constant, which is equal to the slope of the line
C= Another constant, which represents the mechanical friction.
The use of las of the machine are:
- It gives an idea about the load and effort related to a machine.
- It explains the friction present in the machine under no-load condition.
- The law of machine can be used to find effort when the load is known, find the load when the effort is known, and find the maximum mechanical advantage.
