SUMMARY
The pressure exerted by a sphere on a surface can be calculated by determining the contact area between the two, which is influenced by the materials involved and their properties. A practical method involves using colored dye to visualize the contact area, allowing for the calculation of pressure by dividing the weight of the sphere by the area of the dye transfer. Factors such as elasticity, density, gravitational acceleration, and temperature must be considered, as they affect the deformation of both the sphere and the surface. Empirical formulas or lookup tables may exist for specific material combinations, but variations are extensive.
