ASTM A672 covers B70, C70 and L70 grades. Equivalent for each of them do you need?

Chuko Liang of China invented the wheelbarrow.

Given the vector in angle-radius form? y-component=r sin(theta), x-component=r cos(theta)

The centre lathe has only one coaxial tool, whereas the capstan has a rotating

multi tool station with indexer and clutch.

E6013 is a mild-steel, all position, general-purpose welding electrode (rod).

A major cause of decomposition of transformer oil is minor arcing within the transformer. Decomposition results in gas which bubbles towards the top of the transformer and upward into the conservatory tank. Between the transformer and conservator tank is a Buchholz relay, in which this gas collects, causing a mercury switch inside a float to initiate an alarm in the substation. This gas can be collected through a small pipe feeding from the Buchholz relay in order to have it analysed.

I hate questions like this one. Do you know why? Because I fear that the TEACHERS asking the question of their students are either IGNORANT of the subject matter they are supposed to be teaching or are asking a TRICK question of their students, which is almost always intellectually dishonest. Hopefully, it's just a poorly worded question by the poster of the question. Okay, I'll shut up and answer the question. A quantity of cold air can occupy a greater volume of hot air -- if there is more cold air than hot air!!!! If you've got two liters of cold air, that's a greater volume than one liter of hot air!!!!!! But what if you've got 0.1 kilogram of hot air and 0.1 kilogram of cold air? You've got the same amount of matter, right? They have the same mass: 0.1 kg. Will the hot and cold air occupy the same volume? NO!!! The hot air is less dense, which means it occupies MORE volume per unit mass than the cold air. So, if you have equal masses of hot and cold air, the hot air will have greater volume.

In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes

Yes. More power out of the same engine volume, cleaner burn.

Static means 'stationary', or 'not moving'.

Force (load) = Pressure X Area

Do not know the term, Weldolet, but if your question is where or how do you decide where you are going to cut a pipe to add a branch line, then it is a matter of where it is possibe and the easiest to do. It is not always as close to where you would like it, but where it makes the most sense to do it. Depends on the type of pipe involved also. Copper or PVC you can cut any place you want. Steel, you can replace a coupling with a T and a union if it is in the middle of a run. With steel either black or galvanized you will have to add a union or go back to the end of the run and take everything apart.

Weld-o-lets are sized for the diameter of the pipe you are tying into and the diameter of the pipe you are adding. Example: 2" x 3" or 6" x 10". If you need the branch pipe to have a theaded connection you would select a Thread-o-let instead. Sizing is the same. Some o-let's can be used for a range of piping sizes. Example: a 3/4" thread-o-let may have 8-12 marked on it meaning you can weld it on to either 8", 10" or 12" pipe.

Physical properties means the behavior of materials in response to physical forces other than mechanical, such as; Volumetric, thermal, electric and electrochemical properties. Most Ceramics are lighter than metals but heavier than polymers.

Most ceramics have a higher melting point than most metals as it is that some ceramics such as China can with stand high temperatures to about 1200 degrees centigrade. Ceramics also has lower Electrical and Thermal Conductivity than most metals but the range of value is greater in ceramics permitting some ceramics to be used as insulators, for example Porcelain insulators and others as conductors like Lithium-ion conducting glass-ceramics and oxide ceramics.

Thermal expansion is another physical property of ceramics, Ceramic thermal expansion coefficients are less than those of metals but effects are more damaging in ceramics bringing about cracks and other failures(Thermal shock and thermal cracking) as for ceramic materials with relatively high thermal expansion and low thermal conductivity however there is glass ceramics that has low thermal expansion thus resisting thermal shock and thermal cracking, for example Pyrex glass ceramics. Thus the physical properties being but not limited to permeability, elasticity, considerable strength, hardness, brittleness, resistance to chemical attack and thermal shock.

It would be permanently deformed, then break.

Steel toe shoe rating that is related to the force per square inch capacity that the steel toe can withstand.

Without knowledge of the pressure in the air cond. lab. unit you will not be able to calculate the mass flow. Without the mass flow you cannot do any analysis of the system.
