Hello everyone, I am doing a project this year for my Engineering Science option in Terminale S. Basically, the goal is to be able to tilt a treadmill to simulate a slope. We have made a 3D model on Inventor and we would like to calculate the forces that apply to the cylinder if a 100-kilogram person were to stand on the mat. But we don't know how to go about it at all... Please help us by giving us calculations to apply or give us a tip to simulate the forces directly on Inventor. Thank you in advance for your help.
PS: I am attaching the Inventor file of our model.
It is a balanced system subject to 3 forces: the weight of the person, the force of the cylinder and the reaction at the pivot.
The person can stand anywhere on the mat. But, in the worst case, it will be on the end of the mat opposite the pivot. Its weight is of course exerted vertically.
The cylinder being articulated at each end, the applied force will be exerted along the axis of the rod.
From there, you can calculate the moments with respect to the pivot to determine the reaction on the cylinder.
You can optionally determine the reaction on the pivot later by checking the balance of the whole.
