Question
2: A billboard 2 m high x 4 m wide is supported on each end by a pin jointed assembly (bracing not shown for simplification). Total weight of billboard is 32 kN. Given: H = 1m; Angle φ = 60⁰; q = 2.4 kPa.
1. Determine the normal stress (MPa) in strut AB with crosssectional dimension 6 mm x 50 mm.
2. Determine the normal stress (MPa) in strut BC with crosssectional dimension 8 mm x 40 mm.
3. Determine the required diameter (mm) of pin (under double shear) to be used in A or C if the allowable shear stress of the pin is 120 MPa.
