To simplify everything above; it looks like the cylinder is rolling prior to hitting the motors. So whatever energy you give the cylinder through the motor will be both linear momentum and angular momentum - and it looks like you care about hitting 20 mph linearly? If so - is it possible to...

It's difficult for anyone here, myself included, to really gauge what you're going through and the extent to how you feel 'outclassed' within this course... But you said something that resonated with me: I'm from the UK; and here when you're 16-18 years old, you will do 'A-Levels' prior to...

To just elaborate on mfb's answer a bit, we typically define the maximum limiting current (density) in a superconductor by what is called the 'critical current': Jc. Superconductors come in a variety of flavours, and the 'critical current' (density) is intrinsic to each superconductor...

I was preparing for my first year viva, and thought I should ask myself questions that may come up; to test my understanding. My PhD is on superconductivity, and I thought "what happens to the resistance of an object as it approaches absolute zero?". I found some really funny answers to this...

Have a think about it this way Hemant... Think about helium in a balloon; what shape does this balloon want to be? Spherical, no? In real life it isn't always exactly spherical because a number of different effects. Importantly however, it *wants* be spherical. It *wants* to create a shape...
