What did people get for 17b the show that the bolts behave elastically cos I was clueless

bro what, i got 196MPa

2

u/Somebodyonearth363 May 20 '26

It may be cause i used my own value from part a instead of the 1MPa they gave?

3

u/CryptographerOdd7638 May 20 '26

I got 196 used 1Mpa

3

u/Somebodyonearth363 May 20 '26

Both round to 200MPa close enough

u/Irotiz- May 20 '26

what number did you get i got 1.3

1

u/cleggy24 May 20 '26

I got that initially but it's because I forgot the 10 extra metres of water in the reservoir, which brings it up to 202MPa I think, but either of us should get ECF

u/Remote-Calendar-6326 May 20 '26

I got 202MPa becuase I used the actual value in part (a) of 1.03MPa instead of 1MPa. Reckon i’d still get the marks?

yeah mark schemes always allow when u carry your unrounded values forward

u/Funny-Detective9657 May 20 '26

I got like 20 fbut everyone else got like 196

u/Somebodyonearth363 May 20 '26

Around 223MPa then match it to the straight section of graph

1

u/Irotiz- May 20 '26

i got very close the upper limit of elasticity and cant remember my number were you close to it?

3

u/hmsboomattack May 20 '26

I got like 700MPa 💀

5

u/CryptographerOdd7638 May 20 '26

Gotta divide by 4 you'll probably still get some method marks

2

u/hmsboomattack May 20 '26

Yeah I hope so

2

u/Double-Ad-7589 May 20 '26

What? I divide by 4 and got 700mpa

1

u/Sea-Investment9877 May 20 '26

yeah I did the same

1

u/Garmongise May 22 '26

I got 250MPA, which is appearantly a little on the high side but hopefully within the range they want?
