The angle which the normal reaction makes with the resultant reaction is called angle of friction.
-
Which of the following statement is correct?
-
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.)
