Question

Statement for Linked Answer Q.1 & Q.2

A 20⁰ full depth involute spur pinion of 4mm module and 21 teeth is to transmit 15 kW at 960rpm. Its face width is 25mm.                                                                                                            

1. The tangential force transmitted (in N) is

      (a) 3552                                                              (b) 2611

      (c) 1776                                                              (d) 1305

      2.  Given that the tooth geometry factor is 0.32 and the combined effect of dynamic load and allied factors intensifying the stress is 1.5; the minimum allowable stress (in MPa) for the gear material is

      (a) 242.0                                                             (b) 166.5

      (c) 121.0                                                             (d) 74.0
