Using the principles to developed in chapter 3 on equilibrium, one can determine that the tension in cable AB is 143.4 N. A. Determine the moment about the x-axis of this tension force acting on point B. Compare your result with the moment of the weight W of the 15-kg uniform plate about the x-axis.
C. What is the moment of the tension force acting at A about line OB?

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?
