    diameter, d, suatu silinder logam dengan jisimnya, m.

    Rajah 1.1 menunjukkan lima silinder yang disediakan.

    Diagram 1.1 /Rajah 1.1

    A micrometer screw gauge is used to measure the diameter of the cylinder.

    Diagrams 1.2, 1.3, 1.4, 1.5 and 1.6 show the reading, d, of the micrometer screw gauge

    when the diameter of each cylinder is measured.

    Sebuah tolok skru mikrometer digunakan untuk mengukur diameter silinder itu.
