I have a question on axial loads. I can get to a certain point but can't quite work out how to used the forumla properly. The question is
Given that the maximum compressive stress for steel is 235MN/m2. Using a factor of saftey of 3, determin the maximum axial compressive load that can be applied to a steel punch with a 25mm circumferance.
So far i work out we need to find the area of the punch, which we work out diameter first then half it and work out area using pie x r squared. This is fairly easy but now i know the forumla to use but do i need to work out the slenderness ratio first?
cheers
