A developer is having a single-lane raceway constructed with a 100 mph design speed. A curveon the raceway has a radius of 1000-ft, a central angle of 30 degrees, and a PI station at 1125 10.If the design coefficient of side friction is 0.20, determine the superelevation required at the design speed. Compute the degreeof curve, length of curve, PC station, and PT station.

On a average work day more than work place firs are reorted

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.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
