Consider the two plates joined by $20-mm$ bolts as shown below. The top figure is an elevation looking at the connection from teh side and the bottom image is a cross$-$section through the bolts. Ignore the thickness of the plates and assume the forces shown are transferred as shear equally by all bolts. Ignore self$-$weight. The system is in static equilibrium. Ignore selfweight. The figure is not to scale.

and bottom

Determine the following. Enter all values as positive numbers below using the units given.

The shear condition is $=$ Select an answer $vv($single or double$)$ shear.

The critical shear area of one bolt, $A=m{m}^2$

The average shear stress in one bolt, $=$ MPa
