Interference can come from many sources such as other electronic equipment. This outside 'noise' does not affect FM because FM relies on the change in frequency not amplitude and the noise does not affect the frequency.

An induction motor is set up like a squirrel cage with conductors running down the sides, two electromagnets are placed 90 degrees apart with a capacitor between them. The magnets induce a current into the cage and this sets up another field opposing the first one (lenz's law). The two fields...

good torque (for lifting loads) low maintenance (doesn't have brushes or any wearing parts)

I think ceramics are mostly made to shape when they are clay and then fired. Toughened glass is formed by heating the glass and then blasting the outsides of it with cooled air which places the outside in compression and the inside in tension so any force needs to first overcome the...

i divided the force by 2 casue they are 2 cables e= LF EA e= 5 x 2000 (230*10^9 x 27*10^-6) e= 1.61*10^-3 m e= 0.0016mm if im rong let me know. I think you got the area wrong, its (pi x .027^2)/4 OR pi x .0135^2 then you get e = 5 x 2000...

I hate these sort of questions but i'll give it a go... Material 1. The finding of concrete and its uses as a compressive load taker. 2. Ability to reinforce concrete using deformed steel bars giving it good tension properties. 3. High tensile steel cables made of many smaller cables wrapped...

The analogue signal is sampled at at least twice the maximum frequency and the quantised (put into either 0's or 1's depending on what is closer) and OMG!! its digital!

The smaller strands have less likelyhood to be flawed (surface cracks etc) and therefore will stand up to more bending, stretching. It is also better because if one strand breaks than the rest of the strands can take up the slack and the cable will still operate whereas in the single strand if...

Sand Casting. Sand is packed around a finished model and binded so it stays in the same shape. Molten metal is the poured in and allowed to set. The two halves of the sand cavity are taken away leaving the metal. The sand can be reused. Q. Explain the most common type of moulding for polymers

Yeah i'm pretty sure thats right and essentially it is the same way of doing it its just you use the nice simple formula and i did the long way around it, lol

duralumin is an alloy of aluminium and copper and is usually heat treated using precipitation hardening in which it is heated to approx 530 degrees celcius to produce a single phase alloy and then it is quenched to room temp. The second trapped phase slowly precipitates on to the stress planes...

Angle of attack is the angle that a wing or blade (helicopter) is at. When angles above the horizontal are used lift is produced but when angles below the hoizontal are used the craft will go down. A helicopter blade must change its angle of attack every half cycle in order to continue going up...

[B] in another situation, the load on the winch cable is 1100N. the cross sectional area of the cable is 37mm squared and the youngs modulas of the material is 210GPa. calculate the extension that would occur in a 10 meter length of cabel material. show all working out A. E=210*10^9...

The basic three logic gates are AND, OR and NOT. The and gate needs both inputs to be 1 (true) in order toget and output of 1. In all other cases the output is 0. The OR gate only needs only variable to be 1 to get an output of 1. The NOT gate is like an addition to the other two. If the...

hell yeah, just worked it out, got approx 115/120. sooo happy

soooo happy, carved up the trials! I got first in everything!!!! maths 2U (88%) maths 3U (61%) english adv (72%) (tied first) Engineeing Studies (70%) German Cont (80%) Physics (73%) Markers were really harsh and I made sooo many stupid mistakes, haven't got I.T back yet but I'm expecting ~80-90%

yeah evryone at my school went sorta shit but i carved it up, first in everything apart from english, (haven't got that back yet) looking good so far tho.
