3- A bracket is riveted to a column by 6 rivets of equal size as shown in Fig.3 It carries a load of 60 kN at a distance of 200 mm from the centre of the column. If the maximum shear stress in the rivet is limited to 150 MPa, determine the diameter of the rivet. [15 Mark] 60 kN 200 mm 75 m 75 p 50 mm Fig.3 50 rum
