Why Do Overloaded Brakes Emit Flames?

AI Thread Summary

Overloaded brakes can emit flames due to the combustion of materials used in the braking system, particularly when they reach extreme temperatures. The fire results from a chemical reaction involving oxygen and combustible materials, which can include the brake pads or other components. While brakes may glow red hot, the visible flames indicate that some materials are burning off as they are subjected to excessive heat. The use of ablative materials in aircraft brakes may contribute to this phenomenon, as these materials are designed to dissipate heat effectively. Understanding the mechanics behind this can provide insights into brake performance and safety in aviation.

Hello,

I saw this clip:

And i simply wonder what is the stuff that's burning?

Fire is a chemical reaction between oxygen, heat and some combustible material.

So shouldn't the brakes just be glowing red hot?

I'm no expert, but I would guess that the Airbus uses brakes that, when overloaded, shed heat using some kind of ablative materials and that it is this material you see burn away initially at least.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
