Question

You are given a cotton thread and a woolen thread to measure the length of an object. Which thread will you choose for it and why?

Answer 1

Answer:

Cotton thread because it's dimensions are negligible as compared to wool thread and therefore it acts as an ideal measuring instrument. Hence reading measured is more accurate.

Answer 2

Given a cotton thread and a woolen thread to measure the length of an object:

Explanation:

• A fiber, a single filament of natural material, such as cotton, linen or wool, or synthetic material such as nylon, polyester, metallic or mineral fiber, or man-made cellulosic fiber such as viscose, modal, lyocell or other rayon fiber is measured. In terms of linear mass density, the weight of a given length of fiber.
• Various units are used to refer to the measurement of fiber, such as: denier and tex (linear mass density of fiber), super s (fine fiber fineness), wasted count, wool count, linen count (wet spun). (or Number English (Ne)), Cotton Count (or Number English (Ne)), Number Metric (Nm) and Yield (the reciprocal of Denier and Tex).
• A yarn, a spun group of fibers used for weaving, knitting or sewing, is measured in terms of cotton count and yarn density.
• Thread, typically consisting of several yarns plied together to produce a long, thin stitch or strand used in knitting, is measured in the same units as thread.
• Fabric, typically the material produced by weaving, knitting or tying cloth fibers, yarns, or threads, measured in units such as momme, thread count, (a measure of coarseness or fineness of fabric) ends per inch (ep) and as per the choice of Inch (PPI).
