Homework Help Overview

The problem involves a mass of 5 kg tied to two strings attached to a vertical pole, with the strings forming a right angle as the pole rotates. The mass makes 2 revolutions per second, and the discussion centers around calculating the tension in each string and determining the speed at which the lower string goes slack.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants discuss the net forces acting on the mass and the strings, including centripetal force and gravitational force. There are attempts to set up equations based on the forces in both the x and y directions. Some participants suggest drawing free-body diagrams to clarify the forces involved.

Discussion Status

The discussion is ongoing, with various participants exploring different aspects of the problem. Some have provided hints and guidance on how to approach the calculations, while others express confusion regarding the relationships between the forces and the components of tension in the strings.

Contextual Notes

Participants are considering the assumption that the strings have no mass and are discussing the implications of this on the forces acting on the system. There is also mention of the need for visual aids, such as diagrams, to better understand the problem setup.

yah i know that the force due to gravity ( or the tension in y direction) is diff for both strings
but isn't the tension in x direction same
and i think the tension in x direction is the centripetal force on the object which is also in the x direction
which is 790 N

the tension in the strings is at a 45 degree angle. this means the x and y components are equal. no, the x's are not both equal to each other

ok i m confused
y say the x and y are equal
but the xs are not ?
 
  • #34
so can you please give me a clear answer
please please !

the x and y on the US are equal to each other.
the x and y on the LS are different, but equal to themselves.
 
  • #36
ohh okay
i c what u mean
but if the x and y on both r diff
how r they still forming a 90 degree angle at the point they meet on the object

because each rope is at 45 degrees. I'm sorry but i need to go for now. i hope you can get it and if not, i'll be back in a few hours.
