10. a 0.25-m-wide slab of 5052-o aluminum (k=210 mpa, n=0.13) (k=210 mpa, n=0.13) is rolled from a thickness of 30 mm to a thickness of 20 mm on a cold mill with a roll diameter of 600 mm. the coefficient of friction is 0.25. calculate the maximum roll pressure and required roll force. assume the slab width is constant during the process.

20. threshold braking in the vehicle's braking system occurs when a. the brake pedal is pushed, heel on floorboard, with full foot pressure. b. the brakes are exerting full braking power, without traction loss. c. the driver begins pushing down the brake pedal, with moderate slowdown. d. the brakes just begin to take hold with a gradual slowdown.
