Ah sorry I am being dumb today, I was thinking a Newton was a Pascal, think maybe I should take a break from this study for a day ;p
and nope not from the contiguous 48 as much as I would love to live there and study at MIT
I am English just got back into studying I am a Carpenter by trade...
Got exams in January so just wanna make sure im correct the questions read exactly like this
a) The sample of copper wire reached its elastic limit when the stress is 1.4x10^8 Pa and the strain is 0.035 Calculate the Young's Modulus for copper.
My attempt is Y= Stress/Strain => Y=...
Ok guys thx for all the rapid response mucha grazsia i will email my teach now and find out what he wants as it has to be handed in on monday (Arrgggh)
I will update this thread with what his replie is for those that are interested.
Thanks all PF members.
The difference between conductor, semiconductor and isolator is the size of the gap the smaller the better the conductivity conducters can overlap but unfortunatly i need specific numbers of the energy gap value like Si =1.11eV but i need the value of a good conductor not a semiconductor.
What happens to the atoms in a spring when the spring looses its elasticity in hookes law?
I am aware of the hookes law F =-kx but for my assignment i am also to state what happens to the atoms when the spring becomes plastic and deforms how and why?
my asumtion is that they atoms...
