Question

List 2 ways of measuring a curved line

Answer 1

Answer:

• Tie a knot at one end of the thread > Place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight. > Place your thumb at the other end of the measured portion and measure next straighter portion > Repeat the above step till the end of line is reached. Make a knot at the end of the line.> Now, straighten the thread and measure the length of the two knots on a scale.

• The Chord is the distance straight across the curve, measuring straight across from point to point. This measurement should be made with a flat ruler. To measure the depth of the curve, take one half of the chord measurement and at that point measure to the top of the curve.
