I can't get a smaller clamp because I need to attach the clamp to the leg of a treadmill. The leg is fixed, and that is the only clamp that will fit around that. Unfortunately, the other side of the clamp is too big for the pipe size I have. I could get a bigger pipe, but the pipe size I've...

Hello, I am currently doing a project and have ran into a problem. I have a structural fitting (clamp-on tee) that fits around a fixed structure. I am trying to fit an aluminum pipe into it, but the pipe's outer diameter is much smaller than the clamp-on fitting. I'm attach 2 images that show...

So what you're saying is that by unloading body weight using the handle bars would not reduce VO2 max because work would stay the same? So if the user is making themselves lighter, they could keep work the same by running faster. I think I understand the point you're trying to make. Thank you...

Thank you for your response. By unloading, I mean the user makes themselves lighter, reducing the effort needed to keep going. In VO2 testing, the user must keep going until they cannot go anymore. However, if the user makes themselves lighter and reduces how much energy is needed to keep going...

Hello, I am new to the physical therapy field and I have a huge interesting in performance testing, especially VO2 testing. I am currently working on a project involving such testing. I was wondering if anyone knows the effects of unloading during VO2 max testing. For example, if a user...

An example would be a treadmill bar. Let's say I wanted to measure the force a user is applying downward onto the bar, I would place the strain gages in a configuration under the bar, to create a load cell essentially. My goal is to convert the output voltage from such a configuration to a...

So you mean manually applying different known forces, reading the output for each, and then using that relationship to estimate forces depending on what output voltages are recorded?

Hello, I am doing a project where I have 4 strain gages (in a full bridge Wheatstone configuration) and I am continuously recording their output voltages. These strain gages have been installed on an aluminum bar and are recording bending. My question is how to I convert the output voltage...

So the accelerometer can give me rotational velocity of the foot during walking as well? I'm still a beginner with wiring. Should I soder the sensor(s) to the board, then the microcontroller, then connect them? I'm just confused on the order of the connections. So i would just need the...

I'm trying to make a system that will allow me to record the acceleration/velocity of the foot during walking, as well as the rotational velocity of the foot. I'm using the MMA7455 3-Axis Accelerometer Module and the LISY300 Gyroscope Module. I'm not sure how and where to connect these sensors...

Hi, I am an engineering student that needs help using an accelerometer and a gyroscope. I'm not sure where to begin. How can I setup the sensors to output readable data to a computer. Do I use a microcontroller? Do I need to program anything? I am just in need of help. Anything would be...
