So I did my test in pencil, and the supervising lady only told me later on as she walked past me. She didn't give instruction on us using pen's so yeah...
What's the procedure if I have used pencil? Will they still mark it? or..? :/
Shear Stress= Force/Cross-Sectional Area
therefore: 150x10^3/50x5 (its 50 because the length of the punch is 25, and thats half the length the plate)
=600MPa
then: 600MPa/2 (divided by two because the punch is half the plate as above ^ in brackets)
=300MPa
:)
Just wanted to wish everyone all the best for their HSC in 2013, and hope you achieve whatever your goal mark may be.
I'm hoping for a state rank more than anything and I hope I can get it :)
ahhhh I see! Was wondering what those dashed lines at the bottom were..
That's alright, no need to draw it, you've done enough! It helped plenty
Thankyou!
Hey guys, just wondering if anyone could give me a hand with this question in the 2013 Specimen exam paper. I'm usually really good with pictorial drawings, but this one has me really confused :S
All help is appreciated! Thankyou! :)
