Question

4-2 A tension membe For purposes of cutting and gluing, the angle Omust be between 25° and 45o. The allowable stresses on the glued joint in tension and shearP are 7.00 MPa and 4.00 MPa, respectively, determine r is to be constructed of two pieces of plastic glued along plane pq (see figure) (a) the angle Oso as to allow the bar to carry the largest load, assuming that the strength of the glued joint controls the design. (b) the maximum allowable load Pmar if the cross-sectional area of the bar is 250 mm2
