The pulley, as shown in figure B1, is centralised on a shaft that is supported by self-aligning bearings. The shaft deflects by 0.5 mm due to the weight of the pulley. The shaft has a distributed weight of 20 N/m and the flexural stiffness is 1500 Nm². (Note - use gravity g= 9.81 m/s²). 0.7 metres + Figure B1 a) Calculate the frequency and critical speed due to the pulley only, ignoring the distributed weight of the shaft. b) Calculate the frequency and critical speed due to the distributed weight only. c) Calculate the lowest frequency and critical speed considering the pulley and the shaft.
