Question

A short column with a wide-flange shape is subjected to a compressive load that produces a resultant force P = 54.1 kN acting at the midpoint of one flange (see figure). P = 55 kN Cover plate (120 mm x 10 mm) (Part (c) only) 8 mm 200 C mm 12 mm 160 mm ? (a) Determine the maximum tensile and compressive stresses $sigma_t$ and $sigma_c$, respectively, in the column. (Enter your answers in MPa. Use the deformation sign convention.) $sigma_t$ = ____ MPa $sigma_c$ = MPa (b) Locate the neutral axis under this loading condition. (Enter the value of y, in mm, on which this axis lies.) mm (c) Recompute maximum tensile and compressive stresses if a 120 mm x 10 mm cover plate is added to one flange as shown. (Enter your answers in MPa. Use the deformation sign convention.) $sigma_t$ = ____ MPa $sigma_c$ = ____ MPa
