It is a practice question 500 mm400 mmGear 3(600 mm diam)PA250 mmPc20°20°Gear 4(250 mm diam)The rotating solid steel shaft is simply supported by bearings at points O and B. The resultant gear force P₁ = 2500N acts at an angle of 20° from the y-axis. Draw force diagrams and moment diagrams and find the critical point.The shaft is machined from steel with Sy = 490 MPa and Sut = 580 MPa. Using a factor of safety of 3, determine the minimum allowable diameter at the critical section of the shaft based on(a) a static yield analysis using the distortion energy theory (DE), and maximum shear stress theory (MSST)(b) a fatigue-failure analysis (DE-Soderberg Theory). Assume sharp fillet radii at the bearing shoulders for estimating stress-concentration factors.(Assume for rotating shafts the bending is completely reversed with a bending moment amplitude equal to that used for static conditions. The alternating torque is zero.)
