In a traction drive, a 1.1-in.-diameter cylindrical roller is preloaded against a 3.1-in. diameter cylindrical roller. The steel rollers are 1.6 in. wide and the preload force is 32 lb. The axes of the cylinders are parallel. Calculate the width of contact in inches x 10-5 (e. g. if your answer is 0.0012345, submit 123.45). Also determine the maximum value of the subsurface shear stress.
