How do you know if power factor is leading or lagging?
How do you know if power factor is leading or lagging? The key factor of differentiation between leading and lagging power factor is that leading power factor is attained when the load current is in the leading position to that of the supply voltage. While lagging power factor shows that the current lags the voltage […]
What should I expect in an investment banking interview?
What should I expect in an investment banking interview? Many of the technical questions you get will be on basic accounting and valuation. They will ask you questions on discounted cash flow analysis, intrinsic valuation vs. relative valuation, etc. Interviewers may also give you challenging brainteasers to see how you think about problems on the […]
What is glass transition temperature of plastics?
What is glass transition temperature of plastics? 170 K to 500 K. What happens at the glass transition temperature? There is a certain temperature(different for each polymer) called the glass transition temperature, or Tg for short. When the polymer is cooled below this temperature, it becomes hard and brittle, like glass. Some polymers are used […]
Why does plastic deformation occur?
Why does plastic deformation occur? 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 are the different methods of increasing the strength of metals explain briefly? There are […]
What do we call architectural drawings that show the size of the building?
What do we call architectural drawings that show the size of the building? Foundation plan: A drawing that shows the layout and elevation of the building foundation. What are architectural drawings called? Prints of architectural drawings are still sometimes called blueprints, after one of the early processes which produced a white line on blue paper. […]
