AI Thread Summary
To calculate the area under the graph in the shaded region, consider using trapezoidal estimation based on the grid provided in the image. Each square on the grid represents 0.16 Joules, so you can sum the areas of the complete squares and estimate the area of the partial squares. If you're unfamiliar with using a calculator for this purpose, guidance on basic operations can be provided. It's important to demonstrate some effort in understanding the process. Engaging with the material will lead to a better grasp of the concept.

Okay, so my question is: given the picture below, how can I find the area below the graph (in the shaded region) ? It's for a lab that I did in class, but it wasn't until i finished the whole picture that i realized that I didn't know how to calculate the area of this graph.

Thanks.

HINT: Think trapezoids! :)
 
If an estimate is good enough, just notice that each square represents 0.16*1 Nm = 0.16 Joules. Then just add up the squares and estimate for the non-complete squares.

at this point, i really need a definite answer ASAP, perhaps u can teach me how to use a calculator?

Perhaps I am reading this wrong!

You have been given some very sound advise in this thread already. Why don't you show us some effort on your part.
 
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...
