The W27x84 beam shown in the figure is 50 ft long, simply supported and has no laterall bracing between supports. It has a factored uniform load wu = 2.54 k/ft. including self weight. The beam, as is, does not satisfy bending strength requirements (i.e. phiMn < Mu) and needs additional bracing along the beam. (i.e. Lb needs to be reduced from Lb = 50 ft to an acceptable value that makes the beam works in bending). Using the beam design plots/graphs, the minimum number of brace points N needed within the beam is equal to:

A simple supported beam made up of steel with a maximum bending resistance of 250MPa is subjected to a self-weight of P N/mm. In addition to the self-weight, the beam is also subjected to two identical points loads acting at 1/3rd and 2/3rd of the beam span respectively. Find out the magnitude of point loads acting on the beam such that the flexural stresses does not exceed the allowable bending stresses.
