Inspect the torsion capacity for the three sections shown in below, and based on the ACI Code limitations, it is required to compute the following: a) The cracking moment Tcr b) The maximum factored torque Tn that can be applied to each section without using torsional web reinforcement Assume f'c-25 MPa, fy-420 MPa, a 25 mm. concrete cover, and 10 stirrups. The width of the web of the I section is - 009 -700 mm- 400 mm 150 mm Luw oog- -900 mm- -900 mm- -250- 150 mm 150 mm
