If the length L 106 mm what is the total area that would be

If the length L = 106 mm, what is the total area that would be involved in shear failure if the 4 glued pieces of wood shown below would fail by shear?

Solution

As shown, the piece of wood where shear force is applied is under double shear.

Therefore, the total area will be 2A.

A_total=2A

=2*[L*120]

=2*[106*125]

A_total=26500 mm^2
