A T-cross section simply supported beam is loaded by a single concentrated load P as shown. Ignore its own weight. a) Determine the magnitude of the plastic resistance moment (MP) of the cross- section of the beam, where the yield strength of the material is o, = 400 MPa, b) What is the magnitude of the plastic limit load (collapse load) Pe for this structure under this type of loading.
