The figure above shows two spur gears mounted on a shaft at A and C. This shaft gear assembly is supported on two pedestal bearings at D and Brespectively. These bearing supports act as simple supports. Neglect the weight of the shaft and the gears. The force on gear 1 is shown at an angle with respect to the vertical "y" axis and the force on gear 2 (Fc-1000 N) is shown at an angle with respect to the horizontal...

1. The countershaft shown in the Fig QI has two spur gears mounted on it with teeth cut with a 20 pressure angle. The shaft (grooved) is to be made of cold-drawn AISI 1040 steel having Sut= 779 MPa and S,-593 MPa, an elongation of 19% and HB-262. You are asked to size the shaft for safe operation according to DE-Eilliptic criterion by using a factor of safety of 2.5 and a reliability of 99 percent. The stress-concentration factors for...

Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
