Solve the Balance: Meter Stick Mass Calculation

AI Thread Summary
To solve for the mass of the meter stick, consider the moments around the fulcrum. Initially, the meter stick balances at 49.7 cm, indicating its center of mass is there. When a 50g mass is added at 10 cm, the new balance point at 39.2 cm suggests that the moments must equalize. Using the equation for moments (mass times distance), the calculations should yield the correct mass of the meter stick, which is approximately 245g. However, double-checking the calculations and ensuring the moments are set up correctly is crucial for accuracy.

"A meter stick is found to balance at the 49.7cm mark when placed on a fulcrum. When a 50 gram mass is attached at the 10cm mark, the fulcrum must be moved to the 39.2 cm mark for balance. What is the mass of the meter stick?"

thats the question and the last one on my homework and its given me the u-know-what. I've tried workin it - one answer i got was 245g... but some reason i am quite sure its wrong.. so any hints or help would be greeeat :smile:

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...
