Which of the following is NOT a necessary characteristic of gage blocks? Withstand considerable wear must be made from alloy steel made from something that can be accurately sized and finished must be stable and not change that can be accurately sized and finished must be stable and not change size of their own accord Since its adoption as a line standard on an unchanging physical phenomenon. Which of the following was adopted two eliminate the error? electrical current magnetic resonance sound waves wavelength of light Due to uneven wear, what is no longer adjustable on a micrometer? thin able anvil frame barrel Which type of gage blocks should be missed with other gage blocks? carbide steel chromium plated magnetic Which of the following happens as gage blocks wear Pressure needs to be reduced to minimized damage wringing becomes more difficult wringing becomes easier use of oil should be disconnected

Solution

(16) option (B). It is not necessary that it must be made from alloy steel, it can be made from any metal with good required charcteristics

(17) option (D). Wave length of light wave will naver change. Hence, it is adapted.

(18) option (B). Anvil can not be adjutsed due to uneven wear.

(19) option (A). carbide gage blocks, due to their expansion rates
