For most common scales, this is the only stage that crawls about on the plant. Scales may go through one or more generations each year. Small holes in the scales indicate that a parasitic. wasp emerged from them.
What is the purpose of a steel rule?
Steel rules come in rigid and flexible versions. While their primary purpose is accurate measurement, they can also be used as guides for laying out lines, and if rigid enough, for cutting. The thinner, more flexible rules can also be used to measure rounded or cambered work.
What is made of steel rule?
Explanation: Steel Rule is made of Stainless steel.
What does a steel rule measure in?
The rule is a strip of metal graduated in inches and fractions of an inch to give actual measurements. When tolerances of fractional dimensions are required, the steel rule is used. The most commonly used steel rule is the 6″ rule.

What is the most important factor when measuring with a steel rule?
Both the long edges and the ends of steel rules should be ground for straightness and accuracy. Ends that are ground square, and in proper relationship to the graduations allow accurate measurements from the ends of the steel rule. A properly made steel rule will have virtually no error in the graduations.
How do you use steel rule step by step?
To keep it simple, just remember each unit is half the size of the next largest unit. So, if your desired piece is to be 6 1/4 inches long, mark your object at the first, third-longest marking, beyond the sixth inch. Or, if 6 1/16 inches is required, mark the object at the first, shortest marking, after the sixth inch.

Note in figure 3-4 that 1 cubic foot of steel weighs 490 pounds. his weight divided by 12 gives you 40.8, which is the weight (in pounds) of a steel plate 1 foot square and 1 inch thick The fractional portion is normally dropped and 1-inch plate is called a 40-pound plate.
What is the minimum diameter of a circular opening?
The diameter of circular openings is generally restricted to 0.5D. Depth of rectangular openings should not be greater than 0.5D and the length not greater than 1.5D for un-stiffened openings. The clear spacing between such opening should be at least equal the longer dimension of the opening.
What is structural steel and how is it used?
