Question 2: A prop shaft of a heavy-duty truck has two bearings which are positioned at 3 metres from each other. The shaft must rotate at 30 rad/s when the truck travels at the speed of 40 m/s. Such a shaft carries two masses of (MA = 10 kg) and (MB = 5 kg) acting at the extremities of the arms 0.45 m and 0.6 m long, respectively. The planes in which these masses rotate are 1.2 m and 2.4 m, 2 ASSESSOR MODERA respectively, from the left end bearing supporting the shaft. The angle between the arms is 60°. If the masses are balanced by two counter-masses (named x and Y) rotating with the shaft acting at a radius of 0.3 m and placed at 0.3 m from each bearing centre: 2.1. Draw a diagram illustrating the position of masses on the shaft. 2.2. Calculate the dynamic force in Newtons. Tabulate the results. 2.3. Calculate the moment acting on the shaft in Newton-metre. Tabulate the results. 2.4. Determine the magnitude of the Y balance mass using a vector diagram. 2.5 Determine the magnitude of the X balance mass using a vector diagram.
