The discussion centers on understanding the formula Yc = hc/sin 60 in relation to hydrostatic force on an inclined plane. Participants seek clarification on the derivation of this equation and its components, particularly the significance of Yc and hc. Visual aids are requested to enhance comprehension of the concepts involved. There is also a query about the necessity of dividing two shears in the final calculation and the basic definition of a ratio. Overall, the thread emphasizes the need for clearer explanations and visual representations to grasp the topic effectively.
