Homework Help Overview

The problem involves analyzing the forces acting on a group of cheerleaders in a pose, where they are in equilibrium. The original poster seeks to determine various forces, including those exerted on the top cheerleader's hands, the bottom cheerleader's shoulder, and the forces acting on the bottom cheerleader's feet.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to relate the forces to the masses of the cheerleaders and the acceleration due to gravity, questioning whether to use perpendicular or vertical force components. Another participant suggests drawing free body diagrams and resolving forces into their x and y components.

Discussion Status

The discussion is ongoing, with participants exploring different methods to analyze the forces. Some guidance has been offered regarding the use of free body diagrams, but no consensus has been reached on the approach to take.

Contextual Notes

The original poster has indicated a lack of clarity regarding the problem setup and the specific forces to calculate, which may affect their ability to proceed. Additionally, the problem context includes graphical data that is not detailed in the posts.

Hey, I've just started the curriculum at my school and can not seem to figure this problem out.

Homework Statement


Basically, I have the image below of a few cheerleaders doing a pose. They are in complete equilibrium. I have to find the force put on where the top cheerleader's hands are connected to the top cheerleader. I have to find the force put on by the bottom cheerleader to the guys on the sides. I have to find the force that is being put on the bottom guy's shoulder. Also, what is the force that is being put onto the bottom guy's feet. My points are also attached.

Homework Equations



Force = Mass x Acceleration of Gravity.
Pythagorean Theorem.

The Attempt at a Solution



I think that the force that is being put on the top cheerleader from the two guys to the sides is similar to the simple conversion of each of the masses of the cheerleaders time 9.81(the acceleration of gravity.) Now, would I use the value that I get that is the perpendicular to the floor, or would I use the force that has a vertical length. This would just be for the hands. Now, to get the force that the person is putting onto the bottom person from the sides, I though that I would take the mass of the cheerleaders on the sides and figure the horizontal length in Newtons. The

This problem has stumped me. Thanks in advance, if someone may help me out.

Up you go!
 
you should draw the free body diagram of each of them and resolve the resultant forces acting on them into the x and y component
