Question

Questions 5 through 11: FIG 2 shows member of width w and thickness subjected to a tensile force P with two rectangular P glue joints. It is made of a single material with Young's modulus E and Poisson ratio v(shading is used to differentiate the three sections). (Q5 to Q6 1 point each, Q7 to Q11 2 points each) FIG 2 (Questions 5-11) 5) The average shear stress on joint 1 is a) 0 6) The average normal stress on joint 1 is a) 0 7) The average normal stress on joint 2 is 8) The average shear stress on joint 2 is a) Pt/w(t2 b) b) Pb/w(t2 b2) c)P/wt d) P/bt 9) The average shear stress on joint 2 is maximum when e)P/w(t b) a) b 0 10) The load P causes length a to increase by the amount 11) The load P causes length w to decrease by the amount (in magnitude) a) vP/Ew b) vw
