FS EXAM PRACTICE PROBLEMS WITH CORRECT ANSWERS

How much does an Invar tape expand and contract due to change in temperature, compared to a standards steel tape under the same conditions? (a) An Invar tape expands and contracts much more than a steel tape (b) An Invar tape expands and contracts slightly less than a steel tape (c) An Invar tap expands and contracts much less than a steel tape (d) The two tapes expand and contract about the same amount - correct answer(c) An Invar tape will expand and contract much less than a steel tape when exposed to the same change in temperature. Unfortunately, Invar tapes, while extremely accurate, are too fragile for normal use. So they are typically used for measuring baselines or calibrating steel tapes How many pins are in a set of chaining pins? (a) 10 (b) 11
