Q2. Figure Q2 shows a shaft which transmits a power of 48 kW through flat belts. Pulley A is driven by a motor which rotates at 3000 rpm. The diameter of pulley A is 400 mm and that of pulley B is 250 mm. The thickness of the belts is 4 mm and they are made of a material with density of 1100 kg/m3. Assume no sliding between pulleys and belts a) Calculate the speed of the belt and the...
A line shaft supporting two pulleys A and B is shown in Figure (below).
QUESTION 2 A line shaft supporting two pulleys A and B is shown in Figure (below). Power is supplied to the shaft by means of a vertical belt on pulley A, which is then transmitted to pulley B carrying a horizontal belt. The ratio of belt tensions on tight and loose sides is 3:1 and the maximum tension in either belt is limited to 2.7 kN. The maximum belts tension will occur in belt on pulley A due to smaller diameter....

ection 3-6. A shaft driven by an electrical motor is used to rotate an impeller. The conn between the shaft and the impeller involves a keyway and a fillet, as shown in the figure. Assume that the total force needed to rotate the impeller is 5 (11.1 kips) and the shear strength of the cylindrical fillet is 400 MPa (58.0 ksi), Will a fillet with a diameter of 10 mm (0.4 in.) be sufficient to prevent shear yielding? If a...

Question 2: [20 Points) The Figure below shows a portion of a pump that is gear driven at uniform load and speed. The shaft is supported by bearings mounted in the pump housing. The shaft is made of steel, its yield strength is 800 MPa and its ultimate tensile strength is 1000 MPa. The surface of the shaft is machined. Due to the fillet at A, the fatigue bending stress concentration factor is 2.0, the fatigue torsion stress concentration factor...
