A dial indicator does not indicate the diameter of the objec

A dial indicator does not indicate the diameter of the object being measured. The primary datum feature for a runout tolerance must never be a flat surface. Each measurement for circular runout is considered separately. The surface variations permitted by a runout tolerance do not affect the size limits on a controlled surface. Runout tolerance may be applied to internal and external surfaces. Datum targets may be used to establish a datum axis. When a runout tolerance references two datums, the primary datum must establish an axis. Runout variation may exist relative to a datum axis even when a cylinder has perfect form.

Solution

10) True, Dial indicator is used to find the error not the diameter.

11) False, Runnout tolerance can used on flat surface

12) True.

13) True.

14) True, Interal runnout tolerance is provided in internal threads.

15) True . Datum target can be used to establish datum axis. Datum target is used to define the datum point, line or area,

16)False.

17)True.
