A short prismatic member is subjected to load P of100 kips at the corner shown in fig. Analyse the beam and fnd neutral axis and develop fiber stresses and find stresses at vall corner
For each section illustrated, find the second moment of area, the location of the neutral axis, and the distances from the neutral axis to the top and bottom surfaces. Consider that the section is transmitting a positive bending moment about the z axis, M, where M. 1.13 kN m. Determine the resulting stresses at the top and bottom surfaces and at every abrupt change in the cross section. om 6 mm 25 mim 25 1mm Ca) 3y 100 ー75 12.5...
