Question

A certain piston has a diameter of 0.8756 ± 0.001 in. It travels within a cylinder of diameter 0.881 ± 0.001 in. What is the uncertainty in the clearance between piston and cylinder in the sense of exact analysis and approximate analysis?

Hint: Please use Gap function = G = (D_c − D_p) / 2 , where D_c = the diameter of cylinder, D_p = the diameter of piston.

Please fill in the blanks in the below. When you write down, you must enter in the form of x.xxxx. For example, 0. 0012 or 1. 3465.

Exact Analysis: Δ G =

Approximate Analysis: dG =
