Calculate Dumbbell Counter Weight for Correct Exercise Position

Click For Summary
SUMMARY

The discussion focuses on designing a dumbbell support system that maintains the correct exercise starting position while incorporating a counterbalance mechanism. The user, Samuel, seeks guidance on calculating the necessary counterbalance for dumbbells weighing between 15kg and 90kg. Key concepts mentioned include moment arm and torque, which are essential for determining the appropriate counterbalance and pivot equations needed for the design.

PREREQUISITES
  • Understanding of moment arm in physics
  • Knowledge of torque calculations
  • Familiarity with mechanical design principles

Homework Statement



Hi all, First post so please go easy :smile:

I am designing a Dumbbell support that presents the Dumbbell to the user in the correct exercise starting position (1. Shown on the image.) . The problem I am facing is the counter balance to the support. The Dumbbells range from 15kg-90kg and I assume the counterbalance has to match. My question is would it be possible to use an adjustable support (2. Shown on the image.) and what calculations would I need to calculate this?

Homework Equations



I would assume I need counter balance and pivot equations but I have no prior knowledge of this.

The Attempt at a Solution



Unsure, as stated no previous knowledge.

Any information or help would be greatly received,

Thank you in advance,
Samuel

You'll want to investigate the concepts of moment arm, torque.
