The horizontal cross-section of the cast-iron standard of a vertical drilling machine has the form shown. The line of thrust of the drill passes through P. Find the greatest value the thrust may have without the tensile stress exceeding 15 MN/m2. What will be the stress along the face AB? (Cambridge) ANSWER: 17.68 kN; 11.8 MN/m2 compressive.
