Homework Statement I carried out an experiment using a extensometer, had a range of values for the elongation and load. I calculated the value from the data and had 11GPa whereas it should be 200GPa. Do you know what could have gone wrong? Thanks a lot.

I just need to know how to calculate it without having a linear portion on the graph.

Sorry, I misread my sheet, it just says to calculate Young's Modulus. So how would I calculate it for my aluminium data?

How will that work then?

Homework Statement A cylinder fitted with a piston contains air at 1.0 Bar and 17°C. The gas is compressed according to the law PVn = const., until the pressure is 4 bar when the specific volume is found to be 28% of the initial value. Heat is then added to the air at constant pressure until...

I'm doing it for both steel and aluminium, though I've just realized I have to calculate it for the maxiumum load so everything is fine now.

Homework Statement I don't need to give any information, I just need to know the best way to calculate E from a range of values for load and displacement given the length and diameter. I've calculate it for a few values and the value appears to decrease so I'm not sure where to take the value...

Hey, so I've just started learning about AC theory. I understand the reactance part of it, both capacitive and inductive. Although there are a few things I need to clear up. If there's a resistor, capacitor and inductor in series, will the calculated current from each component be the same? I...

Homework Statement A 100 micro F capacitor is discharged through a resistor of resistance 470K Ohms. Determine the 'half-life' of this circuit. The half life being the time it takes for the initial voltage to decrease by 50%. Homework Equations Is my answer correct? If not, what have I...

Homework Statement Homework Equations The Attempt at a Solution I found out the distance between the star and companion which I calculated as 1.11x1010m (Ignoring the mass of the companion).Then I calculated the radius of the stars orbit, using r = vt/2∏ since vt =...

Oh, I worded that wrong sorry. What would happen to the charged particles angular deflection if the electric field force was increased?

Also, if a particle is traveling through a uniform electric field, does anything change as it leaves the field if the electric field strength increases? If you're asked to find the magnitude, is it just the modulus of those values? What is a vector?

Hello, I've just started learning about asymptotes in school. The questions I have are: 1. To find the vertical asymptote, why do you have to equal the denominator to 0? And then find x. 2. "" "" "" horizontal "" , why do you have to divide the numerator and denominator by x? Thank you...

Oh god, of course. I never did do many integratation including fraction, thanks for clearing that up for me though. So whenever you integrate a variable with a coefficient what a fraction, you simply integrate the variable and switch the fraction around and multiply it. Thanks a lot!
