2. A rigid bar ABDE is being attached to a wall via a pin at A and alloy steel rod BC (E = 250 GPa). BC is pin-connected at its end. Loads of 2.5 kN and 1.0 kN are applied at D and E, respectively as shown in Figure Q2. All the pins have a diameter of 10 mm. Determine: a) Normal stress in rod BC b) Shear stress in pin A and C. Pin C is connected in single shear and pin A is in double shear. c) Resultant internal loadings at the midpoint of bar AB.
