Maximum Stress on a wheel in motion

AI Thread Summary
To calculate the maximum stress on a wheel traveling at 180 m/s and weighing 2000 kg upon impact with a solid object, one must determine the force exerted during the collision. The relevant equation for stress is stress = force/area, but additional parameters such as the material's yield strength and modulus of elasticity (E) are crucial for accurate calculations. The discussion highlights the need for a formula to estimate the maximum force transmitted to the wheel during impact. Understanding these factors will aid in designing a wheel that can withstand the calculated stress without exceeding its yield strength. Accurate calculations are essential for ensuring the wheel's safety and performance under extreme conditions.

Homework Statement


I have a vehicle traveling at 180 ms^-1, weighing 2000kg.
I need to calculate the maximum stress that the wheel is likely to sustain if it hits a solid, immovable object at the above speed, so that i can successfully design a wheel which won't go beyond its yield strength.

Does anyone know of any formula to calculate the maximum force transmitted to the wheel


Homework Equations



stress = force/area

The Attempt at a Solution



Im not really sure where to start with the maximum stress.

Any help much appreciated

Cheers
Ed

I would think you'd need to at least know the modulus E of the material to find the max allowable stress?
 

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}...
