    1. The problem statement, all variables and given/known data
    Hi i have the following question a component of 200mm2 cross sectional area is subject to a tensile force of 40kn Determine the tensile stress and the maximum shear stress that exist within the component ? I can work out the shear but how can i work out the maximum Shear ?


    2. Relevant equations
    stress = Force
    area


    3. The attempt at a solution
    stress = 40,000
    0.0002

    = 200MN/m2

    The problem i have is calculating the other stress any help would be gratefully appreciated

    If there's only a tensile force acting, surely the shear stress is 0?

    I dont know it may but i always thought shear stress was present in all compoenets and in fact in a tenisle stress test the test specimen did not actually fail in tensile stress but in shear stress. I may be looking to far into the question can the tensile stress i have calculated also be the maximum shear or not ?

    Thanks in advance
