AI Thread Summary
The discussion centers on whether a rope held horizontally by a person can support a 10 kg mass without sagging. It is suggested that the rope cannot remain perfectly horizontal due to the tension required to balance the weight of the mass. A free body diagram is recommended to visualize the forces acting on the mass, including tension and gravity. The conversation emphasizes the need to write equilibrium equations to analyze the situation mathematically. Ultimately, the conclusion is that as the angle of the rope approaches zero, the tension would need to become infinitely large, making a perfectly horizontal rope impractical.

Homework Statement


In the figure professional wrestler Randy “Macho Man” Savage is suspending a 10 kg mass with a rope between his two hands. Is the strongest member of your team, or even the Macho Man, strong enough to keep a heavy mass stationary and the rope perfectly horizontal? Explain

Homework Equations

The Attempt at a Solution


I don't know how to approach the question.
I'm suspecting that rope cannot be perfectly horizontal for now...

If you had to draw a free body diagram of the 10 kg mass and the tension in the rope required to keep the mass suspended, what would this diagram look like? If you wrote some equilibrium equations for the mass, could you explain your suspicion about the tension required to keep the rope horizontal?
 
What he said. Draw the free body diagram with the string making some angle to the horizontal. Write the equations. Work out what happens if that angle approaches zero.
 

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...
