10) What are five pieces of information that you can find in title block of an engineering book?

Five pieces of information that you can usually find in the title book of an engineering drawling are the company and drawing name, approvals and dates, drawing and revision number, and scale of the drawing.

1)Why is precision measuring so important in manufacturing?

Precision measuring is so important in manufacturing because the parts that are being made have to be within a tolerance. This is because some parts have to be exact or they wont fit.

3) What is the difference between absolute and incremental measurements?

The difference between absolute and incremental coordinates are absolute means that all the coordinates are in one, incremental means that they are positioned step by step.

6) How might the diameter 3.5 differ from 3.500?

The dimensions 3.5 and 3.500 are the same but the 3.500 is more accurate.

8) What are the measurements at B and D in figure 2.7?

The measurements for letter B are, mean= 540 units, maximum= 580 units and the range= 60 units

2) Name three precision measuring tools.

Three precision measuring tools are caliper, micrometer, and metric micrometer.

11) Where would you look for information concerning manufacturing process of special instruction on a drawing?

When looking for information concerning manufacturing processes of special instruction on a drawing you would look at the dimensions and tolerance.

3) how are accuracy and precision related?

Accuracy and precision are related because they are both used during measuring. Accuracy is how close the area is to the middle, precision is when something hits in the same spot but not on target
