 5: The structure shown was designed to support a
30-kN load. It consists of a boom AB with a 30 x 50-mm
rectangular cross section and a rod BC with a 20-mm-diameter
circular cross section. The boom and the rod are connected by
a pin at B and are supported by pins and brackets at A and C,
respectively.
1. Calculate the normal stress in boom AB and rod BC,
indicate if in tension or compression.
2. Calculate the shear stress of pins at A, B and C.
3. Calculate the bearing stresses at A in member AB,
and in the bracket.
