Just out of curiosity has anyone ever come across these questions before as I haven't covered even the basics of it in level 3 so I don't know how to tackle this problem this is a level 4 question.
On my first reaction I think that g sin\Theta is the total for the sin\Theta from the total and r2 is the radius of the disc which in this case is 750mm but I don't understand what k2 is?
Hi there I was wondering if someone can help me on this attachment I am stuck on question 1.3 and 1.4. This was an experiment to see relationship between sin and gradient I have confidently completed the first two questions but it is the last two questions which are troubling with I am finding...
Sorry what I was meant to say was solving the equation isn't really the problem because I can sit till the cow's come home calculating the unknowns I eventually get there but the bit I struggle with is writing the equations and drawing the correct diagram, because when I try to look at notes and...
Isc=
(9+25)*i1 - 25*i2 = 15
-25*i1 + (25+7)*i2 = 0
This Is the bit I didn't understand i took this out of my notes I know here that the value of I2=0.293a, but I didn't quite understand how I worked out I1.
