Hello, I am supposed to find an expression for the general stress wrt height within a truncated cone of lower and upper radii a and b (a>b), pulled down from its vertical axis by a force of the same magnitude as that pulling it up. The diagram implies that the height between the upper and lower base is h (see attached diagram). Attempt at solution: I did (a-b)/h = (a-r)/h' (since the slope is similar even at height h' from lower base of radius a), From which I could find r and hence the difference in the stress: F(1/A_a - 1/A_r) where A_x denotes the surface area of radius x. I am really not sure this is how it should be done. My initial inclination was to use integrals. Should it indeed be done the way it is presented above? Please advise.
