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 […]

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: […]

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 […]

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 […]

How do you derive the deflection of a beam? Assuming that the deflection of the beam is sufficiently small, we can neglect the first derivative y′. Then the differential equation of the elastic line can be written as follows: y′′=M(x)EIord2ydx2=M(x)EI. The bending moment M(x) can be expressed in terms of the known external load q(x) […]

What is considered a kickback? A kickback is an illegal payment intended as compensation for preferential treatment or any other type of improper services received. The kickback may be money, a gift, credit, or anything of value. Kickbacks are often referred to as a type of bribery. How do you identify a kickback? Most kickback […]
