1. A 200mm x 300mm beam has a simple span of 8 meters. It is necessary to place a support at midspan because of the excessive deflection at the center in order to limit the deflection to 12mm and such that the moment at that point is zero. E = 13,800 MPa. a. Determine the load carried by the beam. Express your answer in N/m. b. Compute for the reaction at the support at midspan so that the beam will not deflect at its midpan. c. Find the bending stress of the beam so that it will not deflect at its midspan. W- N/m 4m Pz 200 mm RI 300mm
