The daily maintenance for stations 1, 2, and 3 consumes 10%, 14%, and 12%, respectively,
of the maximum 480 minutes available for each station each day. Determine the optimal

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
