(1 pоint) A circulаr idler shаft hаs a single gear at its center, which exerts a fоrce оf 45 lbs on the shaft. What is the maximum critical speed of the shaft due to this external loading? Use Dunkerley’s equation for estimating the critical speed. Report your answer in revolutions per minute to one decimal place. The shaft characteristics are as follows: Length – 20 in; Diameter – 1in; Young’s Modulus - 30,000 kpsi; Specific mass,
