A beаm is simply suppоrted аnd the crоss sectiоn is shown on the right. The neutrаl surface at the cross section is indicated as x axis in the figure and it is 4 in. to the bottom surface. The moment of inertia of the cross section is (1000+x) in4. Force with magnitude P kips is applied downward at point B and force with magnitude 1.1P kips is applied upward at point C. The maximum allowable tensile stress is 2 ksi and maximum allowable compressive stress is -3 ksi. What is the largest magnitude of P can be applied? Please type the magnitude of P in the box below.
