AI Thread Summary
The problem involves calculating the torque needed for Tom, who weighs 150lb, to lift a 600lb stone lid using a 12ft lever positioned at a 30-degree angle. To lift the stone, the axis of the lever must be placed at a specific point that balances the torques exerted by Tom's weight and the weight of the stone. Understanding the principles of torque and lever mechanics is crucial to solving this problem. The discussion highlights the difficulty in grasping these concepts, emphasizing the need for clear explanations and guidance. Ultimately, finding the correct axis placement is essential for Tom to successfully lift the stone lid.

This problem involves torque, and levers. I am so stuck on this, I really have no idea where to even begin. The problem states:

"Tom weighs 150lb and he wants to lift a 600lb stone lid form a well. We give him a 12ft, unbreakable lever that has one end attached to the stone (at the COM), and a secure axis. He positions the lever at 30 degrees above horizontal to the ground, and places his hands 6 inches from the end of the lever. He hangs from the lever without "jumping around". Where would he need to place the axis to enable him to lift the stone lid?


I don't even know where to start with this problem. It is in our powerpoint on torques. I tried going to get help for this problem at tutoring, but was still unable to understand how to do the problem.

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...
