Ive to work out the uncertainties for youngs modulus.would i take

AI Thread Summary
To calculate the uncertainties for Young's modulus, all measurements should be averaged, and their uncertainties combined appropriately. The length measurement of 1.788 m has an uncertainty of ±0.01 m. For the value of 5.73 x 10^-3, the uncertainty can be derived based on the precision of the measurement. The discussion highlights confusion regarding how to determine the percentage uncertainty in the Young's modulus value of 6.02 x 10^10 Pa. Understanding the propagation of uncertainties in calculations is crucial for accurate results.

Ive to work out the uncertainties for youngs modulus.

would i take all 4 measurements and mutliply then divide by 4 ?

would 1.788m have an uncertain if +/- 0.01 ?

how would i get the uncertainties from 5.73x10-3

im very confused and my tutor isn't helpful at all.
 
Physics news on Phys.org


Basicly my stress and strain are

A = 5.73 x 10-3
L = 1.788m
F = 8.829 kg m s-1
e = 6.36cm or 6.36x10-1m

youngs modulus is 6.02x10(10) Pa
ive to find the % uncertainty in the Young Modulus value

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
