City Guilds Model Questions Vol1 2020 Engineering Question 47
Practice objective / multiple choice question 47 from the 2020 City Guilds Model Questions Vol1 Engineering examination.
A cylindrical steel rod is measured for length and diameter using calibrated instruments. The measured length is \(300.0\) mm with a standard uncertainty of \(\pm0.2\) mm, and the diameter is \(20.00\) mm with a standard uncertainty of \(\pm0.05\) mm. Assuming the uncertainties are uncorrelated, calculate the volume of the rod (in cm³) together with its combined standard uncertainty, and state whether the result satisfies the specification of \(94.2\) cm³ \(\pm0.5\) cm³.
