고체역학 (Beer) — Introduction—Concept of Stress: Problem 1.27

1.27 For the assembly and loading of Prob. 1.7, determine (a) the average shearing stress in the pin at B, (b) the average bearing stress at B in member BD, (c) the average bearing stress at B in member ABC, knowing that this member has a 10 × 50-mm uniform rectangular cross section. Reference (Prob 1.7): Each of the four vertical links has an 8 × 36-mm uniform rectangular cross section, and each of the four pins has a 16-mm diameter. A 20-kN load is applied at point A of the rigid member ABC. Dimensions: \( AB = 0.25 \text{ m} \), \( BC = 0.4 \text{ m} \).
