3. A bracket is attached to a steel channel by means of nine identical rivets as shown in Fig. 3. Determine the diameter of rivets, if the permissible shear stress is 60 N/mm². $P = 60 kN$ Figure 3

Step 1
Since there are nine rivets, the force per rivet is: $F_{rivet} = \frac{60 \times 10^3}{9} N = \frac{20000}{3} N$ Show more…

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 Fig. A load of 100 KN is applied to the bracket at an angle of 60° to the horizontal and the line of action of the load passes through the centre of the bottom rivet. 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? 80 80 80 All dimensions in mm
