AI Thread Summary
To determine the minimum mass required to cause the 36-kg round table to overturn, the condition for overturning must be understood, specifically regarding the center of mass and the base of support. The mass must be positioned between two of the three legs to create a torque that exceeds the stability provided by the table's weight. Calculations involving torque and the distances from the pivot point (the edge of the table) are necessary to find the solution. The discussion highlights confusion about the relevant equations and the principles of balance and stability. Understanding these concepts is crucial for solving the problem effectively.

I am not sure about math that will be best to solve the question, but first things first - do you know what condition must be fulfilled for the table to overturn?

Something about center of mass and base...
 
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...
