Question

give relation between mechanical advantage and velocity ratio for any machine​

Answer 1

Answer:

• As velocity ratio or idealmechanical advantage is a simple ratio of two distances, it also does not have the unit. The friction is not involved in it. ... If the frictional force in the machine increases the efficiency decreases because machines are frictionless in practice, the efficiency of amachine can never be 100%.

• Mechanical advantage is defined as the ratio of resistance overcomes to the effort applied.Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine.
