Center of Gravity: Locate on Uniform Board 20cmx10cm

Click For Summary

Homework Help Overview

The discussion revolves around locating the center of gravity for a uniform board measuring 20cm by 10cm, which has additional masses attached at its corners. The original poster expresses uncertainty about how to approach the problem.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Some participants suggest analyzing the problem by considering one direction on the xy plane at a time, focusing on the contributions of the attached masses and the board's mass. Others inquire about the accuracy of their diagrams related to the problem setup.

Discussion Status

Participants are exploring different methods to determine the center of gravity, with some providing partial calculations and others questioning the correctness of their visual representations. There is no explicit consensus on a final approach yet.

Contextual Notes

The original poster is seeking help under the constraints of a homework assignment, indicating a need for guidance rather than direct solutions. The discussion includes references to specific calculations and diagrams that may not fully represent the problem's requirements.

Center of gravity?

A uniform board 20.0cm x 10.0 cm has a mass of 200g. Masses of 50.0 and 80.0 grams are attached at two corners at the ends of one of the longer sides. Locate the center of gravity.

i have no idea how to solve this help me pls...

you can firstly do it for one direction on xy plane. Firstly work on 50 and 80 for a line from x. then work on 200 and 130 for a line from y. the junction point of these two lines gives you the new center of gravity.
