City Guilds Model Questions Vol1 2023 Engineering Question 33
Practice objective / multiple choice question 33 from the 2023 City Guilds Model Questions Vol1 Engineering examination.
A cylindrical metal rod is measured using a micrometer screw gauge for its diameter and a ruler for its length. The length is recorded as \(150.0\ \text{mm}\) with an uncertainty of \(\pm0.2\ \text{mm}\). The diameter is measured at three equally spaced points: \(12.34\ \text{mm},\ 12.36\ \text{mm},\ 12.35\ \text{mm}\); each measurement has an uncertainty of \(\pm0.01\ \text{mm}\). Assuming the uncertainties are independent and random, determine the best estimate of the volume of the rod and its absolute uncertainty, expressing the result in cubic centimetres (\(\text{cm}^{3}\)) to appropriate significant figures.
