3. A cable winch is driven by a hydraulic motor and reduction gear, whose transmission ratio i=5. The radius of the drum of winch is rw = 0.2 m. a. Calculate the required radian volume for the motor to lift the mass m=5000kg, when the pump pressure p=240bar. b. How large the flow Q into the motor should be to lift the load with speed v=2 m/s? c. What is the power of the motor with maximum load and speed? Losses are not taken into account.
