Thank you for your point of view, But is this applied to walking? Or for a muscle relaxed and a force applied at a certain distance from the fulcrum as in this experiment?

Thank you very much for the answer and the explanation, Yes, exactly what I was meaning. It’s hard to explain what I wanted to find because the project is at the first stage of development. τ = rFsin(θ) If I use the torque should be : τ = 0.14 x (32.6-14) sin(30) ? We want to measure the...

It’s how I wrote, it’s few years I don’t do these kind of topics.

To have the system in balance the force R should be 32.6N? And then the ankle flex just 30 degrees because is limited from gastroc contracture, how is possible to solve it?

Thank you for the diagram, It should be F * 0.14 * sen alfa = R * 0.06 * sen beta , R = F 0.06 sen beta / 0.14 sen alfa, but I don’t know how to mesure the angles. Is it right the equation? I did the scientific high school but I forgot almost everything. And then how to apply the 30...

I should add in the equation the angle and measure the torque I think, with the ankle at 90 degrees, 20 - 8 cm = 12 cm from the center of rotation, the resulting force should be 9.3 N? (14:12 / x:8) 14x8 / 12= 9.3 N I found this formula for the torque, I should subtract 14-9.3 = 4.7N applied...

Thank you for the link, It’s about also a force of torque right?

Good afternoon Kuruman, Thank you very much for your answer, Yes, exactly on that line and should counteract the force applied and on the plantar side of the foot. The image is not exact, the foot should be at 90 normally. The starting point is at 90 degrees of flexion (foot perpendicular to...

Good morning, I’m new to the forum, thank you in advance. I’m an Italian med student based in France. I’m struggling to find an equation for a project that I am following. I should measure the reactive force at the level of the gastrocnemius (shown in the figure, red arrow). I know the force...
