A uniform cube with 100N weight and 20cm side length is placed in the middle of the horizontal square small desktop. If the side length of the small desktop is 10cm, the pressure of the cube on the desktop is zero______ The pressure is______ .

A uniform cube with 100N weight and 20cm side length is placed in the middle of the horizontal square small desktop. If the side length of the small desktop is 10cm, the pressure of the cube on the desktop is zero______ The pressure is______ .

The pressure of the cube on the desktop is equal to the gravity of the cube, f = g = 100N, the stress area is s = L2 = (0.1M) 2 = 0.01m2, the pressure of the cube on the desktop is p = FS = 100n0.01m2 = 10000pa
