Consider the data shown in the Figures below for the hip, knee, and ankle movements. The raw data for 24 subjects in comma-separated format are uploaded in ME239-139 site. 1. Plot an average curve for each set of data; one for the knee, one for the hip and one ankle. 2. Develop an analytical model (equation) for each average plot; one equation for the hip, one for the knee, and one for the ankle. You can choose various equations for different pieces of each plot. 3. Use the model and calculate the stride length 4. Show how you consider a change in the stride length and the velocity in your equations. Hip Knee Ankle
