8. Locate the centroid of the bent wire shown below. The wire is homogeneous and of uniform across section.

A plain scarf joint is used to fabricate a prismatic member to be subjected to pure tension. Calculate the load carrying capacity of the joint if the allowable shear and tensile stresses in the adhesive layer are 26 MPa and 76 MPa, respectively. The normal vector of the inclined section makes an angle of 30 degrees from the centroidal axis of the prismatic member. The cross-sectional area is 300 mm². 30° P

A joint is made by gluing two plywood gussets of thickness t to wood boards. The tensile working stresses are 1200 psi for the plywood and 700 psi for the boards. The working shear stress for the glue is 50 psi. Determine the dimensions b and t so that the joint is as strong as the boards.
