Measurement Reading Quiz: Questions And Answers

The reading recorded on the vernier caliper is 1.64 cm. This can be determined by aligning the zero mark on the vernier scale with the closest mark on the main scale, which is 1.6 cm. Then, counting the number of divisions on the vernier scale that align with the divisions on the main scale, we find that the 4th division on the vernier scale aligns with a division on the main scale. Each division on the vernier scale represents 0.01 cm, so adding 0.04 cm to the main scale reading of 1.6 cm gives a total reading of 1.64 cm.

The reading shown on the micrometer screw gauge is 4.51 mm. This can be determined by looking at the position of the thimble and the main scale. The thimble is aligned with the 4 on the main scale and the line on the thimble is between the 5 and 6 on the main scale, indicating an additional 0.01 mm. Therefore, the total reading is 4.51 mm.

You should always start your measurement from the very beginning of the ruler (0 cm or 0 inches) to ensure accuracy and consistency. Starting at the midpoint or any other point on the ruler may introduce measurement errors. Starting at the end of the ruler is not the correct practice; you should use the 0 cm or 0 inches mark as the starting point. Using any convenient point on the ruler may lead to inconsistent measurements.

The reading shown on the micrometer screw gauge is 5.81 mm. This can be determined by looking at the position of the thimble and the main scale. The thimble is between the 5 and 6 mark on the main scale, and the line on the thimble is aligned with the 0 mark on the main scale. The number on the thimble that aligns with the main scale is 8, indicating a measurement of 0.08 mm. Adding this to the measurement on the main scale (5.73 mm) gives a total reading of 5.81 mm.

Based on the diagram of the micrometer, the reading shown is 2.73 mm. This is determined by looking at the position of the thimble and the main scale. The thimble is aligned with the 2.7 mm mark on the main scale, and one additional division on the thimble corresponds to 0.03 mm. Therefore, the total reading is 2.73 mm.

The precision of a micrometer screw gauge is 0.001 cm, meaning that it can measure up to the nearest thousandth of a centimeter. This indicates that the micrometer screw gauge is capable of providing highly accurate and precise measurements. Therefore, the statement is true.

The diagram shows a Vernier caliper, which is a precise measuring tool. To determine the reading:

Main Scale Reading: The first step is to look at the main scale where the '0' mark of the Vernier scale is. It is between 4 cm and 5 cm, closer to 4 cm.

Vernier Scale Reading: Next, find the line on the Vernier scale that aligns exactly with any line on the main scale. In this case, the 0.7 cm line on the Vernier scale aligns with a line on the main scale.

Now, add the main scale reading (4 cm) to the Vernier scale reading (0.37 cm):

4.00 cm + 0.37 cm = 4.37 cm

Thimble Scale Reading = 0.8 mm



Thus, the corrected total reading should be:

Main Scale Reading = 5 mm

Thimble Scale Reading = 0.8 mm

Total Reading = 5 mm + 0.8 mm = 5.8 mm



So, the correct reading on the micrometer screw gauge is indeed 5.8 mm.

Based on the diagram of the vernier caliper scales, it can be observed that the zero mark on the vernier scale aligns with the 1.2 cm mark on the main scale. Additionally, the 0.06 cm mark on the vernier scale aligns with the 1.26 cm mark on the main scale. Therefore, the reading recorded on the vernier caliper is 1.26 cm.

The precision of a vernier caliper is 0.1 millimeters. This means that the calipers can measure up to one-tenth of a millimeter accurately. The vernier scale on the calipers allows for precise measurements by providing additional decimal places beyond the main scale. Therefore, the calipers can measure with a precision of 0.1 millimeters.
