Why does current stop flowing through a capacitor? Electrical current can not actually flow through a capacitor as it does a resistor or inductor due to the insulating properties of the dielectric material between the two plates. However, the charging and discharging of the two plates gives the effect that current is flowing. What happened […]
How do you find the transfer function of a closed loop system?
How do you find the transfer function of a closed loop system? Closed-loop System Transfer Function To find the transfer function of the closed-loop system above, we must first calculate the output signal θo in terms of the input signal θi. Note that the error signal, θe is also the input to the feed-forward block: […]
How do you match old shingles to new ones?
How do you match old shingles to new ones? If you’re looking to blend new and old shingles, saving shingles from your original roof installation is an excellent first step. If fading isn’t dramatic, your contractor may be able to achieve a uniform look with the same materials. If shingles have faded, try going a […]
What is the difference between a thermoplastic and a thermosetting plastic?
What is the difference between a thermoplastic and a thermosetting plastic? Thermosoftening (also called thermoplastics) are plastics which will soften when heated and can be reshaped. Thermosetting plastics are plastics do not soften on heating. They are used when resistance to heat is important (eg kettles, plugs, laptop chargers etc). What are the main differences […]
How do you find the standard deviation of a uniform distribution?
How do you find the standard deviation of a uniform distribution? The standard deviation of X is σ=√(b−a)212. The probability density function of X is f(x)=1b−a for a≤x≤b. The cumulative distribution function of X is P(X≤x)=x−ab−a. How do you find the standard deviation of a random variable X? For a discrete random variable the standard […]
What is axial coding in Grounded Theory?
What is axial coding in Grounded Theory? Within and inspired by grounded theory, axial coding is the process of relating pieces, or codes, of data to each other. In particular, axial coding makes connections between categories that reveal themes, new categories, or new subcategories. What is a grounded theory approach to research? Grounded theory is […]
How do you create a node in a linked list?
Where is a removed section placed on a drawing?
Where is a removed section placed on a drawing? A removed section is a section that is not direct projection from the view containing the cutting plane – it is located somewhere else in the drawing. In sectioning irregular objects, we may show features that do not lie in a straight line by offsetting, or […]
What are carbide turning inserts used for?
What are carbide turning inserts used for? Carbide inserts are replaceable and usually indexable bits of cemented carbide used in machining steels, cast iron, high temperature alloys, and nonferrous materials. Carbide inserts allow faster machining and leave better finishes on metal parts. What is the major advantage of using insert indexable carbide cutting tools? Carbide […]
