The gears shown in the figure have a module of 12 mm and a 20° pressure angle. The pinion rotates at 951 rev/min clockwise and transmits 163 kW through the idler pair to gear 5 on shaft c. What radial force does gear 4 transmit to gear 5. Give your answer in kN. Do not include units. 187 5 32T x 18T 487

The gears shown in the figure form an ideal transmission mechanism. Shaft a applies 8.7 Nm of torque to the pinion (gear 2), which rotates clockwise at 2,312 revolutions per minute. All of the gears have a 20 degree pressure angle. Gears 2 and 3 have a module of 2.5 mm, while gears 4 and 5 have a module of 4 mm. What is the speed of shaft c?
