The gear train transmits power from a motor to a machine at E. The motor turns at 2750 rpm. The diameter of solid shaft (1) is 1.53 in., the diameter of solid shaft (2) is 1.9 in., and the allowable shear stress for each shaft is 4.4 ksi. Assume NA = 20 teeth, NB=92 teeth, NC=38 teeth, ND=59 teeth. Determine: (a) the maximum power P that can be transmitted by the gear train. (b) the torque TE provided at gear E. (c) the rotation speed omega of gear E.

With increases in magnification, which of the following occur? a. the field of view decreases. b. the ambient illumination decreases. c. the larger parts can be measured. d. the eyepiece must be raised.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
