Centripetal force. Radius is not given. Find tension in each support

Click For Summary

Homework Help Overview

The problem involves calculating the tension in supports for two platforms rotating in a vertical circle, with a specified period and masses for each platform. The radius of the circular path is not provided, leading to uncertainty in the approach to the problem.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster expresses difficulty in finding an equation that accommodates the missing radius. Some participants inquire about the diagram to clarify the setup, while others attempt to describe the arrangement of the platforms and supports.

Discussion Status

The discussion is ongoing, with participants exploring the implications of the missing radius and seeking clarification on the visual representation of the problem. There is a focus on understanding the relationship between the given parameters and the forces involved.

Contextual Notes

Participants note that the problem involves centripetal motion in a vertical plane and that the lack of a radius presents a challenge in applying relevant equations. The original poster has provided some information about the masses and the period of rotation.

There is this problem that I have been trying to do but I just cannot understand how to approach it. I have been doing centripetal problems for hours so maybe I am just tired.
The thing is that I do not see an equation I can use to cancel out radius since the radius is not given.
I have uploaded a file containing a diagram
Help would be aprreciated. THANKS.

."In an amusement park ride a motor rotates two platforms with a period of 4.0 s in a vertical circle. The mass of platform 1 is 1200 kg and 2000 kg for platform 2. Find the tension in each support when the platforms are at the bottom as shown."

When I open the doc I see text but no diagram. Can you describe it in words?
 
l
l Support A is 4.0m
l
------- Platform 1 is 800 kg
l
l
l Support B 3.0 m
l
l
--------- Platform 2 is 1000kg
 
A kind of visual diagram with the strings and platforms is shown above.
