    Elec2015

    Having fun with Emin? :p Yeah it's probably the hardest 2nd year elec course. If you can memorise & apply the relevant formulae and use a Smith Chart you should be fine for the exam (don't need to be too concerned with the derivations, but try to understand what you can). Anyway here's a...

    Maths in electircal engineering

    I agree that it is essential for an engineer to understand how to analyse a circuit from the fundamental principles (Ohm's law, Kirchoff's laws etc) rather than only memorising & applying formulas/solutions, but you'll find that in practice if you're designing a circuit (or trying to understand...

    P = I^2r = V^2/r

    The source of confusion here is which voltage (V) are you talking about when you say P = V^2 / R? And which current (I) are you talking about when you say P = I^2 * R? Say you're delivering AC electrical power from Newcastle to Sydney through two wires (normally 3 wires are used for 3 phase...

    need help with math1141 question

    c) J.x = (mx X v).x (X = cross product) = m(x X v).x = 0 (since x X v is orthogonal to x) The locus of x is described by J.(x - 0) = 0, which describes a plane through the origin, with normal J d) J = (mx X v) |J| = m|(x X v)| = m|x||v| (since x and v are orthogonal in circular...

    moments of inertia

    let initial total kinetic energy = K, K = translational kinetic energy + rotational kinetic energy = 1/2*mv^2 + 1/2*Iw^2 = 1/2*mv^2 + 1/2*0.4*mr^2*w^2 = 1/2*mv^2 + 1/2*0.4*mv^2 (assuming v = rw, i.e. no wheel slipping against the ground) = 0.7*mv^2 Gravitational potential energy increase...

    Help with Maple 8

    If you want the x-axis to go from 0 to 360 degrees, change the x=-4..4 into x=0..2*Pi. Also the restriction on y you've used (y=-4..4) is useless, since this covers the range of the function y = sinx, so you might as well leave it out. Also there's no need for the discont=true in the command...

    pH question

    HCl + NaOH -> NaCl + H<SUB>2</SUB>O You have 0.05*0.1 = 0.005 moles of HCl and 0.02*0.05 = 0.001 moles of NaOH. After the reaction, you'll have 0.004 moles of unreacted HCl remaining. The concentration of HCl is 0.004 moles / 70 mL = 0.057 mol/L = Concentration of H<SUP>+</SUP> pH =...

    math1151 question-vectors

    Two points that lie on the first line are p1 = (14,1,10) and p2 = (4,-1,2) (by inspection) Also, two points that lie on the second line are p3 = (0,9,5) and p4 = (-5,8,1) The two lines are parallel if (p1 - p2) is a scalar multiple of (p3 - p4) p1 - p2 = (10,2,8) p3 - p4 = (5,1,4) So...

    Math 1A

    In the final exam for PHYS1131 you're given 2 test papers, Test 2 and Test 1R. Test 2 is compulsory and worth 40%. Test 1R is optional, and if you score higher in it than in the midsession, then your Test 1R mark will replace your midsession mark (so Test 1R is like a second chance). But I...

    Transformer "design" questions- help!

    i) The current in the generator is 110000/415 A = 265.06 A (using P = V*I) For the transmission line loss to be 10% of the total power, the current in the transmission line (I) is found by: I^2 * R = 0.1 * 110000 I^2 * 0.05 * 50 = 0.1 * 110000 (total length of wire = 50 km) I = 66.3 A...

    Is your lecturer demoralising?

    Is your lecturer Venkat Ramaswamy? I've heard some horror stories about his marking (btw I don't go to UTS).

    need clarification on tuts...

    For maths1131 there aren't any tutes in the 1st week. When I did physics (phys1131, not phys1111) there was a tute in the 1st week. Not sure about the chem and bio subjects (since I haven't done them).

    General Education

    I've done the above two out of that list (Understanding Tax should be GENL5030 not GENT5030). GENL5030 is a real bludge, the assessment consists of a few practical excercises where you've got to call up some tax hotlines to get some info and write up a few short reports, a tax return test...
