1. Calculate the moment in the rectangular beam below associated with the strain of E=8E, and determine the effective moment of inertia (elastic part only) as the fraction of the initial one. Yield stress: 235N/mm² E= 210000N/mm² 30/ 607 30 ** t bunt виш 2. A rectangular hollow section has all four sides of length B and thickness T. Find the plastic moment for bending about an axis x-x passing through its centroid and parallel to two of the sides, assuming that T is very small as compared with B.
