    Strain Stress
AI Thread Summary
The discussion focuses on calculating tensile stress, strain, and Young's modulus for a round bar subjected to a tensile load. The tensile stress calculated is 400 MN/m^2, while the strain is determined to be 0.00375 or 0.375%. The calculated Modulus of Elasticity is 106.67 GN/m^2. The original poster expresses uncertainty about unit setups but believes the numerical answers are correct. Overall, the calculations appear accurate, pending confirmation of unit consistency.

Appreciate if someone can take the time to check my answers to the following question. If wrong, could you point me in the right direction.

A round bar, 800 mm long, CSA 15 mm^2 experiences an applied tensile load of 6 kN and stretches elastically by 3 mm.a) Calculate the tensile stress in the bar.
My answer 400 MN/m^2

b) Calculate the strain on the rod.
My answer 0.00375 or 0.375%

c) Calculate the Modulus of Elasticity of the material.
My answer 106.67 GN/m^2

The answers look correct, except I set the units up different, but the numbers seem okay.
 
Thnx for taking the time.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
