How did the engineers solve the problem? Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work. How can we […]

Does the Fibonacci sequence start at 0 or 1? Yes to both questions. The Fibonacci Sequence can start with {0, 1}, {1, 0} or {1, 1} and the continuing digits will be identical. The Fibonacci Sequence can start with any two numbers of your choice as long as at least one is non-zero. What are […]

Is it normal to have no friends? Know that it’s completely normal to not have friends. It’s not weird, and it’s even common: 1 in 5 have no close friends. Imagine that every fifth person you meet on your next walk has no close friends. Visualizing this can help us feel less weird and alien: […]

How do you calculate Q flow rate? Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at […]

What is the process of producing polymer? The conversion of raw polymers into finished products involves a series of polymer manufacturing processes….Polymer manufacturing processes. 1. MIXING (compounding) Powder, melt, dispersion, solution 2.2 3-D FORMING Thermoforming Moulding: compression, transfer, Injection, blow; rotational 3. FINISHING Machining, decoration, assembly What are thermoplastics two examples? The following are some […]

What is the power consumption of a light bulb? 60 watts How do you determine the power rating of a light bulb? To find the kilowatt-hours your light bulb consumes per month, multiply the kilowatt use by the number of hours it’s on each month. Example 1: The incandescent bulb uses 0.06 kW of power […]

What is ceramic backing in welding? Ceramic backing strips can be used with every weldable material to reduce oxidation and prevent hydrogen inclusion, by providing a heat-reflecting, weld-supporting surface against which to deposit the welding consumable. Gas release gaps reduce porosity by preventing gas-entrapment. Why backing strip is used in welding? A backing (strip) is […]

What factors influence the glass transition temperature of a polymer? Pressure and free volume. Increase in pressure of surrounding leads to decrease in free volume and ultimately high Tg. Other factors like branching, alkyl chain length, bond interaction, flexibility of polymer chain, film thickness etc. also have significant impact on glass transition temperature of polymers. […]

What is machine breakdown? In its simplest form, an equipment breakdown covers a piece of machinery when it stops working due to an internal malfunction or a broken part(s), requiring the repair or replacement of that equipment. What is machine breakdown analysis? This team-based approach to maintenance improvement looks at the failure on a physical […]

What is the example of fusion welding? Examples of fusion welding processes Such processes where heat is applied by means of electric arc are termed as arc welding process. Similarly, all gas welding processes, resistant welding processes, and intense energy welding processes are basically examples of fusion welding. What is advanced welding? Course Description: Advanced […]
