3. A motor is connected by a belt to pulley B. T, is the tight-side tensile force equalto 1800 N. The shaft spins at a constant speed, 650 rpm. The power deliveredby the motor is 12.6 kW. On pulley A, connected to the load, the slack side ofthe belt has a tension equal to th of the tight side.bTT,Bd shaftDimensions are as follows:da200 тm 300 тт | 250 тm |180 тm | 250 тm 26 тmdBdahaftaWe analyzed a problem similar to this on Test 01 using static failure theories. Isthis strictly correct? Because the shaft is spinning, would not a material particlesee a time-varying reversal of the the bending stress as in the R.R. rotating beamtest? Would a particle see a reversal of the torsional shear stress?Assume Sut = 370 MPa and Sy = 300 MPa. Ignore Marin factors. Ignore stressconcentrations. Ignore direct shear stress (that due to V). Find the safety factorswith respect to fatigue and yielding. Be guided by section 6-14 on combinedloading.
