AI Thread Summary
Tarzan, with a mass of 105.4 kg, swings on a vine that can withstand a maximum tension of 1700 N at an angle of 47.5 degrees from the vertical. The discussion centers on whether the vine will survive this swing, with calculations suggesting a need to assess the maximum tension experienced during the swing. Participants emphasize the importance of using relevant equations and creating a force diagram to analyze the situation effectively. There is uncertainty about the calculations and the role of the angle in determining the vine's safety. Overall, a clear understanding of the forces involved is crucial to resolve whether the vine can support Tarzan's weight during the swing.

Homework Statement


Tarzan has a mass of 105.4 kg and is swinging on a vine that has a maximum tension of 1700 N. Will the vine survive is Tarzan swings from an angle of 47.5 degrees from the vertical?

m=105.4 kg
T=1700 N
Angle of 47.5 degrees from vertical

Homework Equations


I would like to have my answer checked because I am not very confident. What role does the angle have in the question?

The Attempt at a Solution


1700 N/ 105.4 kg- 9.8 m/s^2=6.329032258

Hi ewalker31438,

Welcome to Physics Forums.Your relevant equations section contains no relevant equations. What equations from your notes or textbook might be pertinent to the type of problem at hand?

Your attempt at solution does not appear to answer the posed question: will the vine survive? What is it you were trying to calculate? Can you explain what you had in mind with the calculation you've done?

I think that the vine would survive, to answer the question. I was trying to calculate the maximum tension that the vine would have. I have looked through my textbook and notes and have not found anything relevant to answer this question. Should I make a force diagram and use equations from that to solve the question? I am completely lost.

A diagram is always the best place to start. What type of motion is involved? Knowing that will help narrow down the sorts of equations to look for.
 
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...
