When you use a micrometer to measure the diameter of a rod, you obtained a reading 4.01 mm. If you know the zero offset of the micrometer is -9 micrometer, what is the actual diameter (in unit of mm) of the rod?

A washer you needed as a fastener broke and now you need to buy a new one. You used a micrometer screw to measure its dimensions. This screw has a least count of 0.01 mm and you assumed a zero zero reading. (a) For the outside diameter, the sleeve reading was 20 mm and the thimble reading was 36. What is the final reading? (b) For the inside diameter, the sleeve reading was 12 mm and the thimble reading was...

Briefly explain how the micrometer works (i.e. what one full rotation of the rod means, the relationship between “horizontal” and “vertical” increments on the micrometer, and how the distances are converted to a voltage measurement.) What is the relationship between voltage and displacement, as examined in the LVDT experiment? Were the voltage readings within the linear range of the LVDT? After taking a few readings, was the voltage reading still zero when you returned to 0.500 inches on the micrometer?...

Inside the house where the temperature is 20∘C20∘C, we measure the length of an aluminum rod with a micrometer MADE OF STEEL. (A micrometer is a device which measures distances very accurately.) We find the rod to be 10.0000 cm long. If we repeat this measurement outside where the temperature is-13.7 ∘∘C, what result would we obtain? Caution: the size of the micrometer is also affected by the temperature, so we no longer obtain the true length of the rod...
