This project introduces a novel device design that combines a toy car with a paint stirrer, employing the principles of stored energy and mechanical motion. As the car moves, a tube releases water that flows into a bucket, causing it to fall and activate a weight rise mechanism. Detailed energy calculations reveal 4.298 J in the water and 4577 J in the car, with zero stored energy in the counterweight. Challenges such as water pressure, friction, and space constraints were identified, leading to multiple design iterations. Although the project took 7.3 hours, it provided valuable insights into machine design limitations.

Device Design • String – car to paint stirrer • Tube released as car moves • Water flows to bucket • Bucket falls, weight rises
Summary of Stored Energy • 4.298 J in water • .4577 J in the car • Zero stored in counterweight • Datum at table
Design and Construction Issues • Water Pressure • Friction • Space Constraint • Water Flow • Mess Control: water and sand
Conclusions • 7.3 hrs to complete • Found many ways not to build the machine • Weighted car • Smaller tube • Smaller angle • Height of tube • Size of bucket Cost of Project
