A 7,5 kW electric motor (star-delta start) running at the speed of 900 r/min is to drive a laundry machine, which operates 12 hours per day, by means of a simplex chain drive. The laundry machine must run at approximately speed of 308 r/min. Based on the space restrictions, the center-line distance is limited to 400 mm. Specify the length of chain (in mm) to be used as well as the exact center-line distance. Note that the form of lubrication used is TPYE 2.

Determine the belt length of a V-Belt drive used to connect the 8 cm and 14 cm pulley at a center distance of 50 cm
An industrial fan running at 600 rpm is driven by a 25-kW, 960 rpm, induction motor. The pulley mounted on the motor shaft is 270 mm. Center to center distance is 1.5 meters and use f = 0.35. Determine the minimum angle of wrap in rad.

Can you derive the equation of the length of the belt and the angle of wrap between belt and pulley both for open belt and crossed belt.
Q3. Audi’s design of their R8 model is designed in order to have the engine in the rear of the car with the following schematic of their mechanical power transmission. The engine is connected to the gearbox, where gear change occurs and then a driveshaft is used to transfer an equal ratio of power balancing the rear and front wheel power output thus referring to it as an all-wheel drive. The vehicle has been modified by a customer thus resulted to no power transfer to the front wheels although the rear wheels still have the same power output. Using your knowledge, DEFINE and JUSTIFY the possible reasons of why the front drive isn’t functioning. What are the solutions to this fault?
A tachometer has a transfer function of 2.5 V/1000 rpm. The tachometer is physically attached to a motor which is also attached to a 10:1 built in gear box; the tach produces 2V. The figure below is to provide a picture of the system, the numbers are different. Find the velocity of the input shaft. Find the velocity of the output shaft.
