    I1/I2 = N2/N1Φmax = Bmax * AcSingle Phase Transformer Calculations

    I'm getting this for d) Bm = 0.25T Φm = Bm*A Or , A = Φm/Bm = 0.0075/0.25 m2 = (0.0075/0.25)*10000 cm2 = 300 cm2 Thoughts

    Plotting Kinetic Energy of Mass Against Time and Distance

    Anyone able to help with the correct acceleration formula for this problem, like Carlo, i used Newtons second law which ended up giving me 451.19J, more than the work done value so incorrect.

    Moment of Inertia textbook workings don't make sense.

    What a plonker i am, i have been doing 0.08 x10^4 instead of 0.08^4 .. Can you tell i have just started studying again since school. Thanks SteamKing - look out for more amateurish questions coming your way..haha.

    Moment of Inertia textbook workings don't make sense.

    Homework Statement Question is about buckling, so i know i need to work out I (moment of Inertia), which is for a hollow tube. Homework Equations So the paper states..I = (0.08^4 - 0.06^4)∏/64 = 1.37 x 10^-6 m4 When i do that on my calculator, i don't get this answer. Puzzled...
