Pressure exerted by an object through its base :
       weight in Newtons / surface area of its base in contact with the table.

Pressure due to the disc : P1  =  200 N/ π 0.04²  m²
                             bar:    P2  =  110 N / (0.05 * 0.04 m²)          
                            cube:   P3  =  120 N / (0.05 * 0.05 m²)

To convert the pressure in  to dynes,  multiply by 10⁵.

Compare:  P1 : P2 : P3  =   25  :  11 π  :  9.6 π
