Two cylinders A and B, having a weight of 10lb and 5lb, respectively, are attached to the ends of a cord which passes over a 3-lb pulley. If the cylinders are released from rest, determine their speed in t= 0.5 sec. The cord dose not slip on the pully. Neglect the mass of the cord.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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.
