A machine of efficiency 40% has a load 40newtons and an effort of 60newtons.calculate the velocity ratio?

M.A. = Load/Effort

M.A. = 40 N / 60 N
M.A. = 2/3

V.R.= M.A./ Efficiency
V.R.= (2/3) / (40/100)
V.R.= _______

To calculate the velocity ratio of a machine, we need to use the formula:

Velocity Ratio = Effort/Load

Given that the Effort is 60 newtons and the Load is 40 newtons, we can substitute these values into the formula:

Velocity Ratio = 60/40

Now we can simplify the expression:

Velocity Ratio = 3/2

So, the velocity ratio of the machine is 3/2.
