3. A drill uses a 1/8"" drill bit to drill into parts being manufactured. The drill can be treated as a 1/8"" x 1/16"" rectangle that is twisted around to make two flutes. If the drill is made out of high speed steel with a compressive yield strength of 536kpsi and a young’s modulus of 30Mpsi. Determine the critical force if the drill is 6 inches long. Assume that the boundary conditions are fixed free
