SCSPG (Semi-Circle Segmented Path Generator): How to Use and an Example   in Calculating Work of Friction along Curved Path
  A program called SCSPG (Semi-Circle Segmented Path Generator) is presented in this report. How it works is described and an example of it is illustrated using a case of work of friction along a curved path. As a benchmark for the program, work of friction along straight path is calculated and then compared to theoretical prediction.
