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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
