can nobody help ? have i missed some information ? i have comsulted some people at work and they say the structure has no zero force members :/ anyone?

hi all, im having trouble working out the internal forces in this question, i tried before and got stuck working out the forces at joint C. i have been to see my tutor however he is on holiday till after the deadline for this assignment. handy... i was working out the forces by the...

i think I've got it cracked, worked out F7 as 7752.48 and F8 as -15608.7 thanks for your help guys, its much appreciated! :D

thanks again for your comments, spinnor- there isn't F5cos30 when resolving upwards, I am not sure if I've misunderstood, I've looked back over the FBD and i think my method is correct. could you explain what you meant mate? vela- thanks for your reply first of all, i think that you have...

hi spinnor, thanks for your reply. the problem is that the when i equate the two equations to F7 they don't balance ie the value of F7 comes out different for each one. so when i work out F8, which i got as F8= 6219.3 in compression, but then depending on which equation i put the value of F8...

hi guys ive got a problem whils solving a force analysis on a crane truss, when i get to a joint where simultaneous equations are needed. have a look at what I've got and itll make more sense. when i equate the two equations they don't balance. from my previous working i get F2=9810...
