    Chassis Dynos: Measuring Shaft Torque/Power

    Yes I agree that inertial dyno is not most suitable for tuning purposes, but still they are most common, at least tunners in my surroundings use them (they aren't real tunners more "chip" tunners). And my appologise as I mixed inertial and brake dyno as same thing. It is because I found the...

    Chassis Dynos: Measuring Shaft Torque/Power

    well as I know most chassis dynos are brake inertia - thus BHP. Measuring and calculating drivetrain drag is no problem, as drag is in LINEAR coleration with the speed, so you have two choises. el. motor - you apply some power (current) to the el motor (if it is AC motor you must know its...

    Chassis Dynos: Measuring Shaft Torque/Power

    Can anyone explain me what kind of chassis dynos are used to measure shaft torque/power and how they do it. BTW... Things I allready known; I know that inertia brake dynos use a solid disc flywheel of a constant mass and radius and by meassuring time and flwheel speed (rpm), we can...

    Rotational kinetic energy of a solid disk

    yes, my mistake I was in a hurry! so if I am calculating the flywheel kinetic energy this formula will be correct; Wk=m*r^2*rpm^2/4

    Rotational kinetic energy of a solid disk

    Hi, on the net I found some equation, and would like to know if they are correct ones. http://www.upei.ca/~physics/p261/projects/flywheel1/flywheel1.htm http://hyperphysics.phy-astr.gsu.edu/hbase/rke.html Physics: Stored energy = sum of kinetic energy of individual mass...
