Assume the top image to be the simple version of the wheel configuration and the lower one to be the proposed way of wheel arrangement. In the newer version i want to use a heavy metal plate of approx 200gms and a wheel of 50gm instead of a heavy 200gm wheels due to sourcing issues. This is...

Hey , I’m participating in a sailboat race that forbids gas or electric engines. Paddles and oars are popular with smaller boats while racers over 25 feet rely on peddle drives. As we are poor substitutes for engines these devices work but not very well ! My thought is to add a flywheel, as...

I am stuck on what to do to calculate the inertia of a flywheel using the method described. I am supposed to use conservation of energy equations to calculate the inertia. I have a picture of the experiment and also the measurements I have taken. It seems each method I try I get a different...

For a model, I am making I need to know the friction between a motor and a flywheel. The electric motor is on the side of the flywheel and the idea is when this motor turns the flywheel will start to rotate due to the friction between them. I however can not find a good way to calculate this...

I'm wonder how one could calculate the total mega pascals total mega pascals that can be applied to a spinning flywheel before it exceeds its tensile strength example: a cast iron flywheel is spinning at 10,000rpm(Tangential velocity = 104.72) it has a radius of 100mm and a weight of 500g...

I am trying to build a simulation of a car engine and wheels for a game project. My model is currently this: Engine outputs a torque -> this spins up a flywheel over time (the physics step of 1/60s) -> the flywheel is coupled with the clutch and thus transmission -> the transmission multiplies...

Hi there I have been having a go at this question and I'm uncertain if my answer to part b) is valid? The problem is when I plug this into the calculator I get 6.379... revs however this doesn't make sense to me. 2*pi is roughly 6.28 radians so doing 4.061... rads / 6.28 rads = 0.647 revs...

Hey everyone! Was trying to answer this question and was wondering if this was the right way to go about it? Any help would be really appreciated!

I converted 5 minutes to 300 seconds, and movement angle per second as shown on the picture. From here on I am lost, as the angular velocity can't be calculated, as the time given isn't the one in which the flywheel does one rotation. I apologise if I used any expressions wrong, english is not...
