I have already drawn the circle and am happy and confident with it, but the question asks me to determine if failure has occurred and I am unsure of how to tell, I guess I don't know how to read the circle and interpret what it means. Can anyone describe to me how you tell if failure has...

Homework Statement...

I finally got it! need to take f' of both those equations then sub them. Works out to around 65m/s

hehehe yep :blushing:

No it's only showing term 2?

Ah... was 343 your assumption? I used a different value. Q9. Mblock - Mdisplaced fluid - D = 0 Mblock = 4.7 + 3.5 = 8.2kg Or D + E = Mbeaker + M liquid + Mblock 11 = 1 + 1.8 + Mblock Mblock = 11 - 2.8 = 8.2kg

I though Q5 was asking for individual frequencies of the first 3 harmonics (i) open and (ii) closed I used for open f1 = v/2L f2 = 2f1 f3 = 3f1 and closed f1 = v/4L f3 = 3f1 f5 = 5f1

I finally get 65m/s :cry: because I am soooo happy! Only differences are: 5. a) (i) 1st Harm. 7.32Hz 2nd Harm. 14.6Hz 3rd Harm. 22Hz (ii) F1 = 3.66Hz ; f3 = 11Hz f5 = 18.3Hz 9. a) 1237kg/m^3 b) D reads Mblock = 8.2kg E reads Mfluid + Mbeaker = 2.8kg

:redface: completely missed a step I have been doing this assignment all weekend + all friday... I think my brain is officially fried! Thank goodness this is my last question How have you been finding it all? You seem to have a fairly good grasp. Are you on campus?

just doing it now but be buggered if I can figure it out! keep getting 0.33km/hr or 0.0905m/s

yeah I subed the first eq (above post) into second but didn't change km/hr to m/s and made a mathematical error when working it out.

cool, thanks Pat666
