(8%) Problem 10: Suppose an automobile engine can produce 220 N-m of torque, and assume this car is suspended so that the wheels can turn freely. Each wheel acts like a 13 kg disk that has a 0.155 m radius. The tires act like 2.1-kg rings that have inside radii of 0.185 m and outside radii of 0.335 m. The tread of each tire acts like a 8.5-kg hoop of radius 0.32 m. The 11.5-kg axle acts like a solid cylinder that has a 1.85-cm radius. The 30.5-kg drive shaft acts like a solid cylinder that has a 3.35-cm radius. ▷ A Calculate the angular acceleration, in radians per square second, produced by the motor if 95.0% of this torque is applied to the drive shaft, axle, and rear wheels of a car. a = sin() cotan() cos() asin() atan() acotan() cosh() л tan() acos() E sinh() tanh() cotanh() Degrees O Radians Submit Hint ( 7 8 9 HOME ^. 4 5 6 12 3 0 + END VO BACKSPACE DEL CLEAR Feedback - I give up!
