The figure below shows the power transmitted through a gear drive to multiple output shafts. Gear A is mounted on an electric motor with a rotational speed of 600rpm. Gear A drives a simple gear train consisting in gears B, C, D, and E and transfers the input power to each gear to the shaft on which is mounted. The power delivered from shafts B, C, D, and E are: 8hp, 12hp, 5hp, and 5hp, respectively. For simplicity, all gears have a diametral pitch of 3 and the following numbers of teeth: NA=75, NB=15, NC=120, ND=15, NE=36. The expected rotational speed on shaft E is most likely: 375 rpm 600 rpm 1250 rpm 3000 rpm
