AI Drawing Prompt Reference

Draw two cylinders inside a trough with their associated free-body diagrams. The cylinders are generated by rotating circles, and the trough is a polygon. First, sketch the outlines of the cylinders and find their intersection points with the trough. Then, add vectors for gravity, normal force, and friction on the cylinders, along with helper lines and angle markings. Combine all elements to form the complete illustration, showcasing the use of parametric equations and vectors.
