How do you harden teeth with gears? Induction hardening or selective heating may be employed to harden just the gear teeth only, which can be an effective method of reducing the distortion in a gear. Masking of journals and keyways may be employed in case hardening processes to keep them soft and allow for easier […]
What is the maximum shear stress in a thin walled pressurized sphere?
What is the maximum shear stress in a thin walled pressurized sphere? A pressure vessel is assumed to be a thin walled pressure vessel when the thickness of the vessel is less than 1/20 of its radius….List of Equations: Parameter Formula Maximum out-plane shear stress (τmax(out plane)) (pgr)/(2t) Spherical pressure vessel Hoop stress (σ1) (pgr)/(2t) […]
What type of waste is most commonly produced in hospitals?
What type of waste is most commonly produced in hospitals? These are infectious wastes, hazardous wastes, and radioactive wastes. Of these three hospital waste sub-categories, infectious and anatomical wastes — like surgical waste or bloody bandages — make up the majority. Which waste is used in landfilling? Municipal solid waste (MSW) and faecal sludge are […]
What causes crankcase Blowby?
What causes crankcase Blowby? When you combine a large cylinder bore, high cylinder pressure through turbocharging, many hours of use and marginal maintenance, excessive blowby is the result. The leakage of any combustion gases, air, or pressure into the engine’s crankcase is considered blowby. What are crankcase emissions or blowby gases are? The unwanted gases, […]
How do we reduce carbon monoxide?
How do we reduce carbon monoxide? Steps to Reduce Exposure to Carbon Monoxide Keep gas appliances properly adjusted. Consider purchasing a vented space heater when replacing an unvented one. Use proper fuel in kerosene space heaters. Install and use an exhaust fan vented to outdoors over gas stoves. Open flues when fireplaces are in use. […]
How does gravity affect a car?
How does gravity affect a car? Gravity has a major effect on your vehicle when you are driving downhill or uphill. When you are driving uphill, gravity’s power is working against you, meaning it pulls your car the opposite direction, which slows down your car. You will need more engine power in order to stay […]
Why are metals conductive and polymers not conductive?
Why are metals conductive and polymers not conductive? Why are metals better conductors than polymers? These electrons are known as delocalised and so are ‘free to move’ across the surface of the metal. These free movement of electrons allows electricity to pass across a metal. In polymers, no such situation arrises and so electricity cannot […]
What is km in Lineweaver-Burk plot?
What is km in Lineweaver-Burk plot? The y-intercept of the Lineweaver- Burk plot is the reciprocal of maximum velocity. KM: Michaelis-Menten constant or enzyme affinity. The lower the KM the higher the affinity. Graphically the x-intercept of the line is -1/KM. Kcat: turnover number, or reactions per unit time. What happens when there is a […]
What is a monomer What is a polymer?
What is a monomer What is a polymer? All monomers have the capacity to form chemical bonds to at least two other monomer molecules. monomers. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units. How do monomers form polymers?
