[doconnor86]

In the figure shown, the input (driver) gear ‘A’ has 30 teeth and the output (driven) gear ‘B’ has 90 teeth Output gear ‘B’ is rotating at 1000rpm, transmitting a torque of 96 Nm giving a power outputof 10.1 kWAssume the efficiency of the system to be 100%. I have attempted to answe each three questions, please can anyone check my workings? Please see hand written attchements. Many thanks
