u iodiil t lorce the jäws of the micrometer together for fine tuning the measurement? What should you do instead? Should not force laws tarether becau t Could cause d tne rroerro Toso 5. The figures below show readings of a micrometer, Figure (3.a) shows the zero error reading, Figure (3.b) the reading when the micrometer is being used to measure the diameter of a ball. What is the actual diameter of the ball? (include the units in parenthesis) Figure 3.a Figure 3.b Answer: Zero Reading Reading of sleeve Reading of thimble Total reading of the micrometer Actual diameter of the ballExplanation / Answer
Zero reading= 7/50 mm (thimble reads 7 and there are 50 divisions on the circular scale)
Reading of sleeve=5.1 mm
Reading of the thimble=15
Total reading= 5.1+15/50=5.4mm
Actual diameter of the ball=5.4-7/50=5.26 mm
