Extracted text: A shaft made of steel receives 7.5 kW power at 1500 r.p.m. A pulley mounted on the shaft as shown in Fig. has ratio of belt tensions 4. The gear forces are as follows: F,= 1590 N; F, = 580 N Pulley T1 Gear F, A D F, -100- 200- 100 All dimensions in mm. Design the shaft diameter by maximum shear stress theory. The shaft material has the following properties : Ultimate tensile strength = 720 MPa: Yield strength = 380 MPa; Factor of safety = 1.5.
