Unformatted text preview: a between the plane of the joint and the faces of the boards must be between 10 and 40. Under a tensile load P , the normal stress in the boards is 4.9 MPa. (a) What are the normal and shear stresses acting on the glued joint if a 5 20? (b) If the allowable shear stress on the joint is 2.25 MPa, what is the largest permissible value of the angle a ? (c) For what angle a will the shear stress on the glued joint be numerically equal to twice the normal stress on the joint?
