Question

The pipe is stuck in the ground so that when it is pulled upward the frictional force along its length varies linearly from zero at B to fmax (force/length) at C. The pipe has a length L, cross-sectional area A, and the material from which it is made has a modulus of elasticity E. Determine the initial force P required to pull the pipe out. Express your answer as an expression in terms of the variables f, L, A and E and any necessary constants.
