Qu. 08-18 Design a double-dwell cam to move a... Design a double-dwell cam to move a follower from 0 to 2.5 in. in 60°, dwell for 120°, fall 2.5 in. in 30°, and dwell for the remainder. The total cycle must take 4 sec. Size the cam for a 1-in. radius roller follower considering pressure angle and radius of curvature. Use eccentricity only if necessary to balance these functions. Plot both these functions. Draw the cam profile. Repeat this for a flat-faced follower. Which one would you use?

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.
