What affects cutting speed? Factors affecting the calculation of cutting speed are: The material being machined (steel, brass, tool steel, plastic, wood) (see table below) The material the cutter is made from (High-Carbon Steel, high speed steel (HSS), Carbide, Ceramics, and Diamond tools) What are the effects of cutting parameters on tool life? When the […]
What is a crowned road?
What is a crowned road? Crowned roads affect how your motorcycle handles and how your tires wear. On a crowned road, that means the pavement slopes from its highest point at the left side of our lane down to its lowest point on the right edge of the lane. What are the advantages and disadvantages […]
What conditions favor formation of substitutional alloys?
What conditions favor formation of substitutional alloys? What conditions favor formation of substitutional alloys? Substitutional alloys are formed when the two metallic components have similar atomic radii and chemical bonding characteristics. For example silver and gold. What is substitutional alloy? Substitutional alloys are formed when the metallic components have similar atomic radii and chemical-bonding characteristics. […]
What is the relation between elastic constants?
What is the relation between elastic constants? Young’s modulus, bulk modulus and Rigidity modulus of an elastic solid are together called Elastic constants….Elastic constant formula. Formula SI Units The relation between Young’s modulus and bulk modulus E=3K\left ( 1-2\mu \right ) N/m2 or pascal(Pa) What is the interrelationship between the three constants? All three elastic […]
How many volts is a 3 phase?
How many volts is a 3 phase? What’s the difference between single phase and three phase? Electricity is either connected at 230 or 240 volts (single-phase, which accounts for the majority of domestic situations), or 400 and 415 Volts (three-phase). How many cycles does 3 phase current have? In a three-phase system, three circuit conductors […]
What is the best stereospecific conformation for E2 elimination?
What is the best stereospecific conformation for E2 elimination? In an E2 elimination, the new π bond is formed by overlap of the C-H σ bond with the C-X σ* anti-bonding orbital. The two orbitals have to lie in the same plane for best overlap. E2 elimination takes place from the anti-periplanar conformation, as this […]
What causes an engine to knock?
What causes an engine to knock? The knocking sound often occurs when the air-fuel mixture is incorrect, which causes the fuel to burn in uneven pockets rather than uniform bursts. Left untreated, it can cause damage to the piston and cylinder wall. A knocking sound can also be caused by a lack of lubrication in […]
How is the amperage adjusted on a FCA welding machine?
How is the amperage adjusted on a FCA welding machine? how is the amperage adjusted on a FCA welding machine? changes in the wire feed speed automatically change the amperage. How do you adjust amperage on a welder? Pro Tip: A good rule of thumb for setting your stick welder (SMAW) to the approximate right […]
Which crystal structures are close packed?
Which crystal structures are close packed? It turns out that face-centered cubic and hexagonal close-packed crystal structures pack atoms equally tightly. Some metals with hexagonal close-packed crystal structures include cobalt, cadmium, zinc, and the α phase of titanium. What are closed packed structures? The term “closest packed structures” refers to the most tightly packed or […]
Why is ice on wings bad?
Why is ice on wings bad? Ice in flight is bad news. It destroys the smooth flow of air, increasing drag while decreasing the ability of the airfoil to create lift. Ice accumulates on every exposed frontal surface of the airplane—not just on the wings, propeller, and windshield, but also on the antennas, vents, intakes, […]
