The 300 lb force is to be resolved into components along
linesa-a' and b-b'. a) determine the angle a by trigonometryknowing
that the component along line a-a' is to 240 lb. b)what is the
corresponding value of the component along b-b'?

Fluids at rest possess no flow energy. 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.
