In the structure shown, an 8-mm-diameter pin is used at A, and 12-mm-diameter pins are used at B and D. Knowing that the allowable load P is 80 kN. Determine the following; a) The shearing stress in pin A, b) The shearing stress in pin D, c) The largest normal stress in link BD, d) The bearing stress in the link at B.
