A steel bearing is known to have a true diameter of 0.4982 in. In the laboratory, you use a micrometer that is supposed to be accurate to 1/10,000 in. to measure the sphere diameter. You take 10 readings at various rotations of the sphere and obtain the following readings:
0.4923, 0.4924, 0.4921, 0.4921, 0.4920, 0.4922, 0.4921, 0.4922, 0.4923, 0.4922
1. What is the overall accuracy error (systematic error)?
2. Discuss what corrective action, if any, should be taken to make the micrometer more precise.
3. Discuss what corrective action, if any, should be taken to make the micrometer more accurate.
