The beam has one length egual to L and is subjected to an evenly distributed load equal to q. B a) Use the unit load method to solve the statically indeterminate task and prove that the vertical the stock reaction in B is equal to 3qL/8. b) Assume L = 8m, q = 15kN / m, draw moment and shear force diagram D Fokus 10°C
