Given a = v1(t) = 4 cos(377t + 17°) v and b = v2(t) = –20 cos 377t v. report your answer so the magnitude is positive and all angles are in the range of negative 180 degrees to positive 180 degrees.

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.
