(c) A titanium hip replacement ball joint of 23.000 mm diameterwas precision ground and required to be finished to a tolerance of+/- 0.002 mm The inspection procedure resulted in the parts beingmeasured whilst still hot at 80 C after grinding. If thecoefficient of linear expansion of titanium is 10 microns/metre degC, determine 1) The linear expansion relative to the referencetemperature of 20 deg C 2) The overall result of measuring partshot on the finished size and the type of engineering fit that mayresult Comment on the likelihood of the +/- 0.002 mm tolerancebeing obtainable and should a correction factor be applied to themeasurement ?
