Unformatted text preview: moment of inertia, I xx for an ideal beam (no cracks). b) Determine the NA and moment of inertia, I xx , of beam if the beam is cracked and tensile forces are in the steel only. [3] Given: f c = 6 ksi and f y = 60 ksi. The dimensions are b eff = 36 in., b w = 9 in., d = 17 in., h f = 3 in., h=19.5 in. and A s 6 # 9 bars. If the top is in compression and bottom is in tension. a) Determine the centroid (neutral axis, NA) and moment of inertia, I xx for an ideal beam (no cracks). b) Determine the NA and moment of inertia, I xx , of beam if the beam is cracked and tensile forces are in the steel only....
