Required information Skip to question Under normal operating conditions, the electric motor exerts a torque of 2.4 kN·m on shaft AB. Each shaft is solid and take d = 55 mm. Determine the maximum shearing stress in shaft AB. (Round the final answer to one decimal place.) The maximum shearing stress in shaft AB is MPa.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
