고체역학 (Beer) — Introduction—Concept of Stress: Problem 1.61

1.61 For the assembly and loading of Prob. 1.60, determine (a) the average shearing stress in the pin at C, (b) the average bearing stress at C in member BC, (c) the average bearing stress at B in member BC. (Data from Prob. 1.60: Two horizontal 5-kip forces are applied to pin B of the assembly shown. Knowing that a pin of 0.8-in. diameter is used at each connection, determine the maximum value of the average normal stress (a) in link AB, (b) in link BC. Dimensions from Fig. P1.60: Pin diameter \(d = 0.8 \text{ in.}\), member width \(w = 1.8 \text{ in.}\), member thickness \(t = 0.5 \text{ in.}\). Angles: link AB is at \(60^\circ\) with the horizontal, link BC is at \(45^\circ\) with the horizontal.)
