purposes of cutting

Two boards are joined by gluing along a scarf joint, as shown in the figure. For purposes of cutting and gluing, the angle 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 = 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?
