If it is subjected to a bending moment of M = 60 kip ft determine the normal stress in each of the steel reinforcing rods and the maximum normal stress in the concrete. Take Est = 29(10) ksi and Econc = 3.6(103) ksi SOLUTION Since the beam is made of concrete, in the following analysis we will neglect its strength in supporting...

Part Design/size the rectangular cross section of a steel bar which is fixed at one end and carries an axial force of 95 kip at the other end (the weight of the bar itself can be assumed to be small and negligible). The height h of the cross section shall be 1.3 times larger than the base b of it (i.e., h 1.3xb). After finding b and h, round each one of them up to the nearest half of an...
