Micrometer Screw Gauge Worksheet With Solution -

12.50 + (15 × 0.01) = 12.65 mm Explanation: Half-mm visible = add 0.50

0.50 + (25 × 0.01) = 0.75 mm Explanation: Sleeve shows 0 + half-mm line = 0.50 Section B Solutions 6. Sleeve = 1.50 mm, Thimble = 0.42 mm Total = 1.92 mm

The ratchet prevents over-tightening and damage. (T / F) micrometer screw gauge worksheet with solution

Sleeve shows: 5 mm (half-mm line NOT visible) Thimble aligns: 32 divisions Reading = ______ mm

– The ratchet slips when the correct pressure is applied, preventing damage to the screw or object. Sleeve shows: 8 mm (half-mm line visible) Thimble

Sleeve shows: 8 mm (half-mm line visible) Thimble aligns: 3 divisions Reading = ______ mm

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. Sleeve shows: 3 mm (half-mm line NOT visible)

Sleeve shows: 3 mm (half-mm line NOT visible) Thimble aligns: 47 divisions Reading = ______ mm

3.00 + (47 × 0.01) = 3.47 mm (Note: Thimble 47 means 0.47 mm)

Sleeve = 2.00 mm, Thimble = 0.08 mm Total = 2.08 mm
