고체역학 (Beer) — Introduction—Concept of Stress: Problem 1.26

1.26 The hydraulic cylinder CF, which partially controls the position of rod DE, has been locked in the position shown. Member BD is 15 mm thick and is connected at C to the vertical rod by a 9-mm-diameter bolt. Knowing that P = 2 kN and θ = 75°, determine (a) the average shearing stress in the bolt, (b) the bearing stress at C in member BD.
