# Maximum load P

Please see the attached file.

Three plates are joined with a 12 mm diameter pin as shown. Determine the maximum load P that can be transmitted by the joint if:

a) The maximum normal stress on a cross-section of the plates at the pin must not exceed 400 MPa.

b) The maximum bearing stress between a plate and the pin must not exceed 600 MPa.

c) The maximum shear stress on a cross-section of the pin must not exceed 250 MPa.

d) The punching shear resistance of the material in the top and bottom plates is 350 MPa.

The figure shown is a lap joint connection using a rivet or bolt connector.

a) The plates can fail by tension. The governing equation for this is:

(please see the attached file)

Where:

(please see the attached file)

At = t(b-nd)

And t= thickness, b=plate width, n=number of ...
