Hand calculating this problem takes several steps. Here is how I would do it. 1) The thin parts are doing all of the deflecting, so... -

Like.
The early ones did Old EUC - SBU With the low foot pegs, the EUC couldn't be tilted much, and combined with the narrow tire couldn't... -

Just the rate of acceleration or deceleration versus how far offset the riders center of mass from the tire contact patch has to be...

EUC stability. When riding at sufficient speed, about 8 mph | 12 kph for most EUCs, they become self-balancing left + right. An...

EUCs (Electric unicycles are programmed to remain vertical (or at some user set fixed angle), using accelerometers and gyros, similar to...

I can ride a real unicycle. One cannot spontaneously lean forward. Instead, one pedals slightly back. This moves the contact point...

Are you interested in the dynamics of maintaining the balance too, or just the overall torque balance numbers? I've never tried riding...

Actually they do hold the wood pieces together. They're called Cam Lock fasteners: (from...

Lnewqban reacted to anuttarasammyak's post in the thread Undergrad Conservation of angular momentum in the iceskater example with Like.
The angular momentum before and after the change in the moment of inertia is conserved: $$M=I_1\omega_1=I_2\omega_2$$ Assuming ##I_1 >...

Lnewqban replied to the thread Undergrad Conservation of angular momentum in the iceskater example.That inwards movement of the limbs reduces the total angular inertia of the ice-skater (the centers of masses of the arms acquire less...

Lnewqban reacted to timeuser84's post in the thread Undergrad Question about the absorption of heat based on color with Like.
This was more than enough knowledge, thank you for the quick responses.

Lnewqban reacted to Baluncore's post in the thread Undergrad Question about the absorption of heat based on color with Like.
Three different parts of the spectrum need to be considered. 1. Ultraviolet, UV. 2. Visible light colour. 3. Infrared, heat, IR. The...

Lnewqban reacted to Steve4Physics's post in the thread Chain falling out of a horizontal tube onto a table with Like.
@NTesla, the last part of the question on the screenshot is missing. So here’s what (I believe) it should say: "... At a certain...
