Question

6. Describe the method you would use to find the thickness of a sheet of paper of your science book.

Answer 1

Answer:

The thickness of a sheet of paper can be measured by folding the sheet and then measuring the thickness.To measure thickness of the sheet, the sheet is folded a large number of times.

Answer 2

Explanation:

A screw gauge is a device for exactly measuring the diameter of a skinny twine or the thickness of a sheet of paper. A screw gauge may be used to make greater particular duration measurements of as much as 0.01 mm or 0.05 mm.

A Screw Gauge is a greater particular tool than Vernier Calipers. A screw has threads on it.

Pitch:

The thread gauge pitch can be defined as the distance traveled by the spindle per revolution.

Pitch of the Screw = (Distance traveled by the screw)/(Number of Full rotations taken)

Method:

• Determines the pitch and minimum count of the screw gauge.
• Use the ratchet head to separate the screw  from the anvil, insert a lead shot, and then replace the screw. Stop in place so that the ratchet slides without moving the bolt.
• Count the number of uncovered pitch scale divisions visible  by the edge of the cap. The pitch scale value (PSR) is represented by the letter N.
• Count the number (n) of circular scale divisions that cross the reference line.

Calculate the total thickness of paper by using the equation:

$t = P.S.R. + H.S.R. \pm Z.C.$

H.S.R. = Circular scale reading(n) x least count.

and apply zero correction (Z.C.)in each case.
