urgent - need help with torque
i know that torque = force x radius (for a wheel of a car driving)
and I've found a couple of equations on power in relation to torque.
but from that first equation what exactly is the force?
i actually went throught thinking that the force was mass*gravity for a while before i realized they were talking about a different force.
could someone please tell me how to get this force value? (in order to find the torque, or is it the torque value i need to find the speed)
also from the equation i found:
power = torque * angular speed (rev/min)
i looked up the angular speed and i found that
angular speed = tangential velocity / radius of revolution
but the text said that the angular speed was in "radians / second"
then which units did i need the velocity and the radius into finish with radians?
i have another power-torque equation where:
Power = torque * 2 * pi * rotational speed
is this any different at all (as in it has to be applied to a different problem scenario) from the equation i just stated above?
anything else that will help me understand the torque and power (in relation to torque) is really appreciated
