Question

which of the following statements is not true of telescoping gauges? a) they can be used to measure bore diameters b) they are often used in conjunction with an outside micrometer c) they can produce actual readings up to 150 mm d) a typical telescoping gauge consists of two plungers, a handle, and a lock screw

Explanation:

Telescoping gauges are used to measure bore diameters and are often used with an outside micrometer. A typical one has two plungers, a handle, and a lock - screw. They don't produce actual readings directly; they are set in the bore and then measured with an outside micrometer.

Answer:

C. They can produce actual readings up to 150 mm
