The bar da is rigid and is originally held in the horizontal
position when the weight w is
supported from c. if the weight causes b to be displaced downward
0.025 in., determine the
strain in wires de and bc. assume that the wires bc and de have an
area of 0.002 in2, and
e = 29,000 ksi.

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?
