three 50 mm by 100 mm full-sized timbers are fastened by 5-mm diameter bolts spaced at at pitch of 40 mm. If the allowable flexural stress in timber is 8 MPa and the allowable shrea stress is 100 MPa, determine the maximun concentrated load that can be applied at the midpoint of a 3-m simple span. Neglect the weight of the beam.
