Acylindrical hole is bored through a steel block, and a cylindrical piston is machined to fit into the hole. the diameter of the hole is 20.04 ± 0.01 cm, and the diameter of the piston is 19.92 ± 0.04 cm. the clearance is one-half the difference between the diameters. estimate the clearance and find the uncertainty in the estimate.

The diameter of the hole is 20.04 ± 0.01 cm

The diameter of the piston is 19.92 ± 0.04 cm.

We are given that The clearance is one-half the difference between the diameters.

So, Clearance =

                      =

Uncertainty in the estimate =  

                                              =  

So, Clearance with uncertainty is

Hence  the clearance is 0.06 and the uncertainty in the estimate. is 0.025

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
