I started my aerospace enginnering degree this year but have missed the first 7 weeks of lectures due to being in hospital, i was sent all lecture notes but am strugling with my mech module. I have my first assignment questions due in this week and am having dificulty thought you guys might be able to give me some guidance! Thanks(adsbygoogle = window.adsbygoogle || []).push({});

Question?

Two cables AC and BC are tied together and loaded at C as shown. The maximum allowable tension in each cable is 800N.

Find the magnitude of the largest force P Which could be applied at C.

Also find the corresponding value of the angle α

I have attached a word document of the diagram!

My workings so far have been something like this:

I have drawn a free body diagram to help make things more simple!

I have resolved the forces and renamed bc to T1 and ac T2

Apply the equilibrium conditions-

ΣFx=0= T1cos50- T2cos35 (+Pα) unsure if (+Pcosα) is nessacery as i have never completed an angular question like this!

ΣFy=0= T1sin50 + T2sin35 - Psinα

Next i am gusing as i am teaching myself from a book! i use these to equations as simultaneous equations and solve them. I was wondering if i should use the value of 800N for T1 and T2 as this is there max allowable tension but i am not sure!

Please can some one point me in the right direction, thanks alot your help is much apreciated.
