Shear stress, Direct stress and factor of safety -- help please

Homework Statement

A load of 10kN is applied to a tensile member as shown in fig 2, and is carried at the joint by 3 steel rivets of 12mm diameter spaced equally at 40mm centres. The angle of the joint is 60 degrees to the axis of the load and the rivet material has a Modulus of Rigidity G = 85GN/m2...

Relevant Equations

Shear stress calculation, Trig

hello, I'm new to this forum and I'm looking for some much needed help/guidance as i have absolutely no idea on how to workout my assignment! any help would be much appreciated

We are not allowed to provide any tutorial help until you show your best efforts to work the problem. Maybe go back and re-read this part of your textbook and revidew your class notes, and look for ways that you can start to approach this problem. Thanks.

The info seems incomplete to me: we are not told how the 10kN is distributed. So I would assume it is spread equally over the three rivets.
First, try to answer:
What does direct stress mean here?
What does shear stress on a joint mean?
