Chapter 2, Problem 2.6.20P
A tension member is to be constructed of two pieces or plastic glued along plane pq (see figure). For purposes of cutting and gluing, the angle ?? must be between 25 and 45. The allowable stresses on the glued joint in tension and shear are 5.0 MPa and 3.0 MPa, respectively
(a) Determine the angle it so that the bar will carry the largest load P. (Assume that the strength of the slued joint controls the design.)
(b) Determine the maximum allowable load ?? if the cross-sectional area of the bar is 225
