4–41. the 10-mm-diameter steel bolt is surrounded by a bronze sleeve. the outer diameter of this sleeve is 20 mm, and its inner diameter is 10 mm. if the yield stress for the steel is (sy)st = 640 mpa, and for the bronze (sy)br = 520 mpa, determine the magnitude of the largest elastic load p that can be applied to the assembly. est = 200 gpa, ebr = 100 gpa.

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
