Factor of safety for a 10mm bolt under 9kN angled load

[Danyolb]

Question: The material for the bolt shown in the angled joint has an ultimate tensile stress of 600MPa and a shear strength of 250MPa. The diameter of the bolt is 10mm. Determine the factor of safety. Assume F=9KN.

Stress = Applied Force/ cross-sectional area
Factor of safety = ultimate tensile strength / actual tensile stress

The bolt is subject to both tensile and shear stresses. You have to determine each. What have you tried so far?

I'm also stuck on virtually the same question as Danyolb's (different values though), so can anyone help in showing the full workings of the following please:

Question: The material for the bolt shown in the angled joint has an ultimate tensile strength of 600MPa and a shear strength of 250MPa. The diameter of the bolt is 10mm. Assume K=9kN. Determine (1) Factor of safety in tension, (2) Factor of safety in shear & (3) State which factor of safety is safer of the two.

Thanks.

Matty, you are going to have show some attempt before we can help. You should first determine the vector components of the force acting along the axis of the bolt and perpendicular to its axis.
