spindle.
Just before the reading of d is taken, the gap is closed using the ratchet
and not the thimble.
Explain why the gap is closed in this way.

where ρ is the density of the metal.
Values of d and μ are used to calculate ρ.
The percentage uncertainty in d is
1.2%. The percentage uncertainty
in μ is 2.0%.
Calculate the percentage uncertainty in the result for ρ.
