There are three candidate cross sections for a beam that is to span a 20 ft space. The loading is given below. The load P can move along the beam so you must account for the maximum possible moment and the maximum possible shear (the load may not be in the same position for these two maximums). The beams are made of wood planks, each 1x12". They are nailed together with 3" long nails. Each nail has a 100 lb shear capacity. The wood has a maximum tensile/compression design strength of 1000 psi and a maximum design shear strength of 75 psi. Do not use safety factors. NEGLEC T BEAM WEIGHT.
