Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I have been given the questions below as part of some revision before we begin mechanics next term. I have looked back through my notes and I seem to be missing the notes on calculating the forces.

So far I know

XZ = 9.49m

ZY = 4.24

Angle x = 18.4

Angle y = 45

Angle Z = 116.6

I think the value of force in XY is -5Kn but I am struggling to calculate the force in rafter XZ.

Any help would be appreciated =D and thanks in advance
