What problems may result by using an electrode at too low a current setting? What problems may result by using an electrode at too low a current setting? poor fusion and poor arc stability. Why is it usually better to make a weld in the flat position? This flat horizontal position allows for the maximum […]
Why do mechanical and physical properties depend on the density of PM parts?
Why do mechanical and physical properties depend on the density of PM parts? Explain why the mechanical and physical properties depend on their density. Mechanical properties rely on their density to maximize metal particle contact and cohesion which affects a metal’s strength, ductility, elastic modulus, and toughness. Describe the relative advantage of cold isostatic pressing. […]
Why is my computer always updating when I shut down?
Why is my computer always updating when I shut down? This could be because of your “Windows Update” settings. If it is configured to run frequently (daily), then the available updates downloaded in the temp location and will get installed when you shutting down your machine. What happens when you turn off your computer when […]
What is the 90 90 rule?
What is the 90 90 rule? Knowledge at a glance: The 90-90 rule points out experiences in effort estimation, according to which 90% of work performed and an estimated 10% of remaining effort in practice become 180% (90%+90%). … What is a good rule of thumb for when to abstract code out into a separate […]
Are brake rotors balanced?
Are brake rotors balanced? Some may notice little notches on the side of their new brake rotors. Those milled areas are a result of the process used to balance rotors, called “mill balancing”. A mill balanced brake rotor reduces vibration and is meaningful to the whole brake system. Brake rotors are made from castings. What […]
Why does temperature increase when CO2 increases?
Why does temperature increase when CO2 increases? When there’s more CO2 in the atmosphere, it makes the atmosphere warmer by trapping heat. Since humans are adding more CO2 to the atmosphere, that helps explain why temperatures are increasing around the world. What happens to temperature when carbon dioxide increases? Scientists say that doubling pre-industrial carbon […]
What is heat rate in powerplant?
What is heat rate in powerplant? Heat rate is one measure of the efficiency of electrical generators/power plants that convert a fuel into heat and into electricity. The heat rate is the amount of energy used by an electrical generator/power plant to generate one kilowatthour (kWh) of electricity. If the heat rate is 7,500 Btu, […]
How do you calculate the pitch diameter of a spur gear?
How do you find the angular acceleration of a rod?
How do you find the angular acceleration of a rod? 3 Answers Sum of the forces on body equals mass times acceleration at the center of gravity. ∑i→Fi=m→aC. Ax=maxAy−mg=may. Sum of torques about center of gravity equals moment of inertia times angular acceleration. ∑i(→Mi+(→ri−→rC)×→Fi)=IC→α Acceleration of point A must be zero. →aA=→aC+→α×(→rA−→rC)+→ω×(→vA−→vC) How do you […]
What material is helmet made of?
What material is helmet made of? Styrofoam and Koroyd Also known as Expanded Polystyrene (EPS), Styrofoam is one of the most popular materials used for the inner lining in a helmet. It is also commonly known as thermocol and has always been reliable considering its impact-absorbing qualities. What are motorcycle helmets made from? The common […]
