1. A rectangular post which is made up of two blocks of wood glued together along a joint inclined at an angle a = 30°. Given the working stress for wood= 13053.4 psi normal stress developed in glue=17404.5 psi shearing stress in glue= 21 755.7 psi axial force= 8 kN nd: a. What is the minimum cross-sectional area of wood (m²), without exceeding the normal and shear stresses in the glue? b. What angle will maximize and minimize both normal and shearing stresses?
