The aircraft A with radar detection equipment is flying horizontally at an altitude of 12.2 km and is increasing its speed at the rate of 1.76 m/s each second. Its radar locks onto an aircraft B flying in the same direction and in the same vertical plane at an altitude of 15.3 km. If A has a speed of 1110 km/h at the instant when = 23°, determine the values of and at this same instant if B has a constant speed of 1670 km/h.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
