Extracted text: Problem 1.6-4 The inclined ladder AB supports a house painter (82 kg) at C and the self weight (q = 36 N/m) of the ladder itself. Each ladder rail (1, = 4 mm) is supported by a shoe (f, = 5 mm) which is attached to the ladder rail by a bolt of diameter d, = 8 mm. B B, (a) Find support reactions at A and B. (b) Find the resultant force in the shoe bolt at A. (c) Find maximum average shear (7) and bearing (o,) stresses in the shoe bolt at A. Typical rung H =7 m -Ladder rail (1, = 4 mm) Shoe bolt at A Shoe bolt (d, = 8 mm) Ladder shoe (1, = 5 mm) A a = 1.8 m b = 0.7 m Ay Assume no slip at A Section at base E==============: = 36 N/m
