The simply supported beam shown in Fig. P.14.13 carries two symmetrically placed transverse loads, W. A rectangular strain gauge rosette positioned at the point P gave strain readings as follows: €, = -222×10 “, ep=-213x10-6, ɛ=45×10-6. Also the direct stress at P due to an external axial compressive load is 7 N/mm². Calculate the magnitude of the transverse load. Take E=31000 N/mm², v=0.2. Ans. W=98.1 kN
