Constant Force Force constant Graph

AI Thread Summary

The discussion focuses on calculating the force constant (k) from a graph where the y-axis represents force in Newtons and the x-axis represents displacement in meters. The user calculates k as 3.70 N/m using the formula k = 1/0.27, questioning its accuracy. It is confirmed that the slope of the graph, calculated as Δy/Δx, indeed represents the force constant k. The user seeks further validation of their calculation and understanding of the graph's interpretation. Accurate interpretation of the graph is essential for determining the correct value of k.

Find the force constant fron the graph

k = 1/0.27 = 3.70 n/m ( is this ok )

plese I want your help

I can't see the graph very well...but slope is \frac{\Delta\;y}{\Delta\;x} so as long as the y-axis is Force (in N) and the x-axis is displacement (in m), then the slope would be N/m or k.

slope = k

I find the slope but is k is correct ?

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 '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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
