I have created a 2 circuits, that run off a voltage produced from a proximity probe (they have their own power suplies), one that takes the voltage straight off and then outputs the voltage on a digital display, and one that needs to be stepped down in the ratio 5:1 so that the voltage can be...

"A 20 kg block, m1, is sliding on a 10 kg block, m2. The blocks are on a 20º slope and are connected by a light string looped over a pulley. " All surfaces are frictionless and the string/pulley are massless. I understand that the 20kg block should slide down since it should have a greater...

Can someone please explain to me how to draw the PP, I mean besides drawing the lines which i think i can understand, how do you decide how to draw the direction of the phase portrait? I mean for example we have: x'=y and y'=-2x^3, obviously those are parabolas and hyperbolas, now the...
