Find Force to Topple Right Circular Cone of Mass m & Angle a

AI Thread Summary
To determine the minimum force required to topple a right circular cone of mass m and semi-vertical angle α placed on a rough surface, one must analyze the forces and torques acting on the cone. The force should be applied at the tip of the cone, and sufficient friction must be assumed to prevent slipping. Participants are encouraged to share their initial attempts at solving the problem to facilitate guidance. The discussion emphasizes the importance of understanding the mechanics involved rather than simply providing a solution. Engaging in problem-solving collaboratively can enhance comprehension of the underlying physics concepts.

A Right Circular uniform Solid cone of mass m and semi vertical angle a(alpha) is placed over a rough horizontal surface. Assuming friction to be sufficient to prevent slipping, find the minimum force that can be applied at the tip of the cone such that it just topples.

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'
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'
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...
