沒有任何力學基礎的力學分析

1. 我想買櫃子
可是書很多又很重

2. Single Cell
Loading : 25Kg
25/ 2 = 12.5Kg 25/ 2 = 12.5Kg
Ground

3. Single Cell plus one plus one plus one
Loading : 25x4 = 100Kg
單一垂直層板平均負載
100/ 5 =20 Kg
Ground

4. Single Cell plus one plus one plus one
and stack it once
Loading : 25x4 = 100Kg
Loading : 25x4 = 100Kg
100/ 5 =20 Kg
100/ 5 =20 Kg
+ 上層負載20Kg
= 40 Kg
(每個垂直層板負載) Ground

5. finally …
Weight : 25x4 = 100Kg
單一垂直層板平均負載
100/ 5 =20 Kg Weight : 25x4 = 100Kg
(100 + 100 )/ 5
= 40 Kg Weight : 25x4 = 100Kg
(100 + 100 +100) / 5
= 60 Kg Weight : 25x4 = 100Kg
(100 + 100 + 100+100)
/5= 80 Kg Ground
