2. For a cantilever beam of length L continuous at the support and unrestrained against torsion at the support and free at the end, the effective length l is equal to
5. If R is the reaction on the bearing plate, the minimum moment of. inertia of the bearing stiffener provided at the support of a plate girder of overall depth D, the maximum thickness of the compression flange T, carrying total load W, is
6. If P is the allowable bending stress in a slab, whose greater and lesser projections from the column faces, are A and B, the thickness (t) of the slab base, is (where w is the intensity of earth pressure.)
