Please be neat and legible to receive rating. thank you

. A motor is connected by a belt to pulley B. T2 is the tight-side tensile force equal to 1800 N. The shaft spins at a constant speed, 650 rpm. The power delivered by the motor is 12.6 kW. On pulley A, connected to the load, the slack side of the belt has a tension equal to 5th of the tight side. b lae A lo TL T3 T2 TA d B d. shaft x dB Dimensions are as follows: a b с 200 mm 300 mm 250 mm da 180 mm dB 250 mm dshaft 26 mm
We analyzed a problem similar to this on Test 01 using static failure theories. Is this strictly correct? Because the shaft is spinning, would not a material particle see a time-varying reversal of the the bending stress as in the R.R. rotating beam test? Would a particle see a reversal of the torsional shear stress? Assume Sut = 370 MPa and Sy = 300 MPa. Ignore Marin factors. Ignore stress concentrations. Ignore direct shear stress (that due to V). Find the safety factors with respect to fatigue and yielding. Be guided by section 6-14 on combined loading.
