5. A beam has a square cross-section, a x a, where a is the linear dimension, and is subject to a pure bending moment, M. M is known with an uncertainty of +8% and a is known with an uncertainty of +9%. The strength of the material is known to an uncertainty of ±5%. Find the minimum design factor such that the beam is guaranteed not to fail.

some value P, and the final deflection in the direction of the load is A, the load does work U, =PA on the structure. By conservation of energy, this work is stored in the elastic deformation energy of the structure, U¡ . For a truss, the internal strain energy is the sum of the axial strain energies in all the elements. This gives the equation N²L PA =E 2AE where N is the internal axial force in each member.
