Homework Help: Maximum Stress on a wheel in motion

  1. Mar 23, 2009 #1
    1. The problem statement, all variables and given/known data
    I have a vehicle travelling 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 wont go beyond its yield strength.

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

    2. Relevant equations

    stress = force/area

    3. The attempt at a solution

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

    Any help much appreciated

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