AI Thread Summary
To calculate the frequency of a simple pendulum with a length of 80cm, the user derived a period of 4/7π seconds. They then applied the formula f=1/period, converting the length to 0.8m, resulting in a frequency of 0.577Hz. Other participants noted that while the method is generally correct, the final frequency value should be double-checked for accuracy. Additionally, they inquired about the number of oscillations corresponding to the calculated time. Accurate calculations are essential for confirming the frequency of oscillation.

I'm asked to Calculate the frequency of oscillation of a simple pendulum of length 80cm.

As its a pendulum I used

To calculate the time. To which I got 4/7π

I then used f=1/period and converted 80cm to 0.8m and got a frequency of 0.577Hz, is this correct ?

In future be sure to make use of the formatting template! This is a requirement as stated in the forum rules (which you read of course, right?).

Regarding your question, your method is fine but you might want to recheck the final value. Could be just a typo rather than a calculation error...
 
How many oscillations takes for this time value?
 

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...
