With this information, some insights into the efficiencies of the rocket engine were found. https://images.squarespace-cdn.com/content/v1/687941ab992fb43810d87e31/59e948b9-8a12-44ba-b554-5b185ce77626/Picture1.png Portfolio - Full Flow Rocket Engine Analysis https://ziviello.com/portfolio/h-ohm-strength monthly 0.5 2025-09-11 https://images.squarespace-cdn.com/content/v1/687941ab992fb43810d87e31/f8c1f961-2d1a-4f5a-961b-03ed76f33d5c/Gear+Prototype1.jpg Portfolio - H-Ohm Strength - The prototyping of a cable input system with a motor providing electronic resistance that emulated a piece of commercial gym equipment. This was the first step toward our goal of a portable cable unit. We were able to demonstrate that a continuous electronic resistance could be geared up or down depending on the attached gear ratio. Materials and Processes: 3D printed parts, laser-cut acrylic sheeting, O-Drive M8325s (torque control motor), variable power supply, Arduino UNO https://images.squarespace-cdn.com/content/v1/687941ab992fb43810d87e31/d091cbc3-1366-43eb-8c88-25ed44dd3279/combined.png Portfolio - H-Ohm Strength - Prototyping the selection of different gear ratios and a discrete, variable, transmission, took several iterations. This was a complex process, though not as bad as a automotive transmission with continuously engaged gears. Our design assumed that when the device was not in operation, the gears were not rotation, so NO CLUTCH! Materials and Processes: 3D Prints, Metric hardware https://images.squarespace-cdn.com/content/v1/687941ab992fb43810d87e31/505d2a20-b04d-4db3-8ab6-4f8d9cc201b2/Eng1.png Portfolio - H-Ohm Strength - Alongside the gear ratio placement, the gear engagers had to be designed to allow for seamless transitions between the different gear ratios. This was perhaps one of the most difficult steps in the process, as the engagers could only be manipulated along their transmission shafts and had to seamlessly rotate into its respective gear ratios. Whatever it is, the way you tell your story online can make all the difference.
