Average = (6.25 + 6.27 + 6.26) ÷ 3 = 18.78 ÷ 3 = 6.26 mm Section C Answers 10. False – The thimble typically has 50 divisions , each = 0.01 mm. Some have 100 (0.001 mm resolution), but standard school ones use 50. The ratchet prevents over-tightening and damage
Sleeve shows: 8 mm (half-mm line visible) Thimble aligns: 3 divisions Reading = ______ mm Some have 100 (0
Zero error = +0.04 mm (excess). True thickness = Scale reading – Zero error = 5.72 – 0.04 = 5.68 mm If zero error were negative (-0.04), you would add.
