例1如图1,正方体物块放在水平地面.若如甲那样截去上边虚线部分的两小块,则对地压强将;若如乙那样截去下边虚线部分的两小块,则对地压强将.(填“变大”、“变小”或“不变”)分析如果那样截去两小块,显然对地压力减小,而受力面积不变,据P=F/S易知P将减小. Example 1 In Figure 1, the cubes are placed on the horizontal ground. If two small pieces of the dotted line are clipped as in A, then the pressure on the ground will be; if the two small pieces of the dotted line are clipped as in B, then Ground pressure will be analyzed (fill in “larger”, “smaller” or “unchanged”) If you cut two small pieces, obviously the pressure on the ground decreases, and the bearing area remains unchanged, according to P=F/S It is easy to know that P will decrease.
