Case Scenario:  As an engineer working in a mechanical engineering department you are working on power transmission systems that are connected by a variety of methods. Working in the design team you will assist one of the engineers in your department to carryout calculations to verify designs and your calculations will be checked and signed off by a senior engineer within the department. You are requested to carry out calculations on the following mechanical power systems. Task : 1 The diagram to the left shows a stationery flat belt pulley and the data for this system is provided in the table below. For this pulley system you are required to: i. calculate the tension in each side of the belt when stationery, ii. determine the power transmitted when the belt is on the point of slipping on the driving wheel. Task: 2 The information provided above shows the data for a multi-plate clutch system. i. Using constant (or uniform) wear theory, determine the maximum power that the clutch can transmit without slippage. ii. Using constant (or uniform) pressure theory, determine the maximum power that the clutch can transmit without slippage. Task: 3 The compound gear train above shows A as the input gear and D as the output gear. Use the data provided in the table to determine:

1. the output speed and direction
2. the output power
3. the fixing torque

B.  The epicyclic gearbox shown above has a fixed outer gear which consists of 80 teeth. The planet gears have 30 teeth. The input rotates at a speed of 100 RPM clockwise with a torque of 45Nm, the gearbox is 70% efficient. Calculate:

1.  The gearbox ratio
2. The output speed
3.  The power output
4. The holding torque

Task: 4 To achieve M3 you must present your work with formula, full calculations and units shown in tasks 1-3. You will present your work in a professional way so that your Senior Engineer can check them and sign-off your results.
