Which of the following functions are performed by limit switches? The limit switch then regulates the electrical circuit that controls the machine and its moving parts. These switches can be used as pilot devices for magnetic starter control circuits, allowing them to start, stop, slow down, or accelerate the functions of an electric motor. What […]
What purpose does the case of a rifle or handgun cartridge serve?
What purpose does the case of a rifle or handgun cartridge serve? The main defining component of the cartridge is the case, which gives the cartridge its shape and serves as the integrating housing for other functional components — it acts as a container for the propellant powders and also serve as a protective shell […]
What is continuity equation for fluid flow?
What is continuity equation for fluid flow? A continuity equation is the mathematical way to express this kind of statement. For example, the continuity equation for electric charge states that the amount of electric charge in any volume of space can only change by the amount of electric current flowing into or out of that […]
At what depth is ground temperature constant?
At what depth is ground temperature constant? 12 to 40 feet What is the temperature below ground? “The temperature of the Earth down 20 or 30 feet is a relatively constant number year-round, somewhere between 50 and 60 degrees” F, says John Kelly, the COO of the Geothermal Exchange Organization, a nonprofit trade organization in […]
What is the structure of monomers?
What is the structure of monomers? Monomers are atoms or small molecules that bond together to form more complex structures such as polymers. There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. What does monomer mean? Monomer, a molecule of any of a class of compounds, mostly organic, that […]
Can a non licensed person be the sole owner of an engineering business?
Can a non licensed person be the sole owner of an engineering business? 6. Can an unlicensed person own an engineering business? An unlicensed person cannot be the sole owner of an engineering business offering civil (including structural and geotechnical), electrical, or mechanical services.

What are the procedures before boarding a flight?
What are the procedures before boarding a flight? Passengers must do a web check-in and print out a boarding pass at home. They must also download and print baggage tags/identification numbers to be attached to their luggage. In the initial phase of flights being resumed, only one hand bag and one check-in bag will be […]
What is a fishbone diagram used for?
What is a fishbone diagram used for? A cause and effect diagram, often called a “fishbone” diagram, can help in brainstorming to identify possible causes of a problem and in sorting ideas into useful categories. A fishbone diagram is a visual way to look at cause and effect. How do you use the fishbone tool […]
How do you calculate the length of a common rafter?
How do you calculate the length of a common rafter? Just multiply the rise or run by the appropriate rafter length factor corresponding to your roof pitch. For example, if your roof pitch is 30ﹾ and your run is 2.4m then reading from the table the rafter length factor is 1.15. Multiply this factor by […]
What is meant by plastic deformation?
What is meant by plastic deformation? Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist. What is meant by elasticity and plasticity? Elasticity is the property of a body […]
