AI Thread Summary
To determine the common factors of the numbers 3.5, 5.4, 8.2, 8.9, 13.6, 14.7, 17.1, 22.9, 28.3, and 31.8, multiplying them by 10 to convert them into integers can simplify the process of finding the Greatest Common Divisor (GCD). Online GCD calculators can assist in this task. However, this method may not be suitable if the numbers are rounded or truncated, as it could overlook potential divisors due to experimental error. It's important to consider the nature of the data when applying this approach. Understanding these factors can help in accurately determining common factors.

3.5, 5.4, 8.2, 8.9, 13.6, 14.7, 17.1 22.9, 28.3, 31.8.

is there any easier way then by hand :\

thanks for any help

You could look for the Greatest Common Divisor (GCD) if you first multiply all the values by 10 in order to make them integers. There are GCD applets on the web if you do a search.

The method may be inappropriate if your values are rounded or truncated measured data values, as it will fail to find a value that is a 'divisor' within experimental error but is not an exact divisor of the given numbers.
 

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...
