Q2) A flat belt drive system is to be) designed for an application in which the input shaft speed is 1725 rpm, the driven shaft speed is to be approximately 960 rpm, and the power to be transmitted has been estimated as 2.5kW. The driven machine has been evaluated and found to have characteristics of moderate shock loading during operation. The desired center distance between driving and driven pulleys is approximately 0.5m. The recommended pulley diameter is 110mm. The belt is made of polyamid with density of 0.95g/cc and the coefficient of friction is 0.8. The limiting design-allowable tension per unit width for the polyamide is 613ON/m.a. If 5mm-thick belt material were chosen for this application, what belt width would be required?b. What initial tension would be required for ?proper operation

Transmission of single screw ships. A sketch and describe the functionality of all the main components; from the prime-mover through to the propeller. List the main propulsive losses and give an approximate magnitude to each.

A three-blade propeller of a diameter of 1.5 m has a rotational speed is 60 Hz, the activityfactor AF is 200 and its static torque coefficient is 0.05. The propeller’s integrated liftcoefficient is 0.3.  Explain whether the thrust of a fixed pitch propeller changes with the flight speed and inwhat way. You may wish to use sketches to illustrate your explanation.
