Using the calf raise exercise Numerical analysis: Estimate the necessary biomechanical parameters based on the available data. Use regression equations $($tables$)$ to calculate the position of the centre of gravity and the weight of the segments. Determine numerically the load on the target muscle and the corresponding joint. Present all steps of the calculation.

Here are the $6$ steps from the lectures. $1.$ Acknowledge the problem, write down the assignment, schematic drawing $2.$ Identify the body$($point$)3.$ Release the bod. $($a$)$ Determine external Forces $($b$)$ Determine the internal forces $4.$ Write the equations of equilibrium $5.$ Verify the solvability $6.$ The solution if the equation of equilibrium

$2$nd Class Lever. This is what i have so far. Could you please check if this is ok and what the equations will look like. Please note that the numbers are all made up and can be adjusted. Thank you.
