Kirchhoff's Law 27 Aug 2013 | 05:51 am

When you start going around a loop to try and determine whether to add or subtract each voltage in that loop, how do you decide which? For example see the diagram just above Q7. http://www.facstaff.b...

Can you Convert these units? 27 Aug 2013 | 05:50 am

Dear reader, I thought I was getting the hang of converting units but came across a thermal conductivity value and the unit was given in: [BTU/hr-ft-R] :eek: I assume the 'R' means 'Rankine'. I wan...

Best algorithm for an object that moves across an area 27 Aug 2013 | 05:48 am

Imagine a rectangular plane with dimensions X and Y. On that plane is a car. The car is about Z meters wide (the front bumper width, or up-down width in the image below). The car travels at a velocity...
