    Lawn/Garden Determining Ramp Length for Ground Clearance

    Got some 6 ft ramps from a local store. Works perfect.

    Lawn/Garden Determining Ramp Length for Ground Clearance

    I haven't really started to look yet, as I didn't know how long they needed to be.

    Lawn/Garden Determining Ramp Length for Ground Clearance

    Hey all. I'm looking to buy a zero-turn mower and I need to build/purchase a ramp to get it into my shed for storage. Exact model is this one. I need to figure out how long of a ramp I need to make sure the mower doesn't bottom out when driving up and down the ramp. Mower stats: Wheelbase...

    When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy

    If you spill a bunch of batteries into a stream, are the volts flowing now?

    I believe the 'speed' is referring to the FPS of the camera.

    Don't worry. It's filled with foam pellets so it doesn't hurt when it hits you. :wink:

    Nice!

    I Why are continuously emitting radio pulsars not detected?

    I wonder if a rotating neutron star would emit much RF radiation if its magnetic poles coincide with its physical poles. @Ken G any idea?

    B Generator shaft rotation through spring and magnet (Is this feasible in Physics?)

    I'm not sure what to tell you that hasn't already been said. You cannot use the motion of the bike to charge the same battery you are using to power the bike, except during regenerative braking.

    B Generator shaft rotation through spring and magnet (Is this feasible in Physics?)

    I don't know what you're trying to say with this.

    B Generator shaft rotation through spring and magnet (Is this feasible in Physics?)

    Let's say the battery outputs 100 watts to the circuit that includes the generator. The generator will receive 95ish watts thanks to losses in the battery and the rest of the circuit. Then the generator will output 90ish watts, again due to various losses (resistance, radiative losses, etc)...

    Hair's influence on the brain

    Nice. I'm bald, so now I have an excuse to go inside instead of mow my yard. "My brain is too hot because I don't have hair to cool it down, Honey!!"

    Speculative theory

    It's fundamentally flawed, as such a model doesn't match our observations about the current and past state of the universe. As PeroK said, take a deeper look into what we know about the BBT and how we know it and you'll see why we model the big bang the way we do. Thread locked, since personal...

    Obviously you cannot use the battery's electricity to charge itself, so I hope that's not what you were trying to do. You cannot even use the motion of the bicycle unless you're recovering energy during braking.
