The figure below shows a gear reduction unit that uses the countershaft. Gear A receives power from another gear with the transmitted force FA = 1500N applied at the 20° pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force FB at the pressure angle shown. The designer plans to use a brittle material (gray cast iron) for the design. If a factor of safety of 3 is to be used for the design. Specify a suitable material for this design using the Modified Mohr 1 Theory.
