Decode the following; identify the head type and rivet length for following: i. AN470AD6-8 ii. AN426DD6-10 A bracket in the form of a plate is fitted to a column by means of four rivets of the same size, as shown in figure 1. A load of 20 kN is applied to the bracket. If the maximum shear stress for the material of the rivet is 70 MPa, find the diameter of rivets. What will be the thickness of the plate if the crushing stress is 100 MPa? 20 kN -80 mm- 100 mm 40 mm 80 mm
