ok im building this contraption. Its a wheelie simulator. Lets your practice clutching up a wheelie and holding it at the balance point. Its basically gonna be something for events, maybe a moneymaking thing at Daytona Bike week who knows.
the way it works is its a heavy inertia wheel, and the bike is attached via a custom axle

I got my hands on some freebie automotive dynos the other day at work.

the problem is this. Im gonna use two adjacent dynos at 50kg each. The radius of these hollow dynos is 10 cm.

Heres the equation for "moment of inertia" ... moment of inertia=mass*radius(squared)

from what i understand "moment of inertia" is the rotational equivalent of regular linear mass.



my dynos measurements are as follows:

Radius of dyno: .1 meter (10 cm)
Mass of dyno : 50kg

when i plug this into I = MR(squared I get 1. Does that mean that pushing a 50kg dyno is the same as pushing a 1kg weight in a straight line ?

i cant be doing this right
