A timber beam of rectangular cross section 250 mm depth x 50 mm width is simply supported over a span of 3 m. If the permissible bending stress is 5 MPa determine the maximum allowable point load (not uniform load) that the beam may carry if the load is applied at midspan.
In Q2 the bending moment that causes a bending stress of 5 MPa is: Select one: O a. 2.4 - 2.5 kN-m O b. 2.7 -2.9 kN-m O c. 2.5 - 2.7 kN-m
