2 受軸力桿件 Axially Loaded Members
第一節 Introduction 第二節 Changes in Lengths under Uniform Conditions 第三節 Changes in Lengths under Non-uniform Conditions 第四節 Statically Indeterminate Structures 第五節 Thermal Stresses and Misfits

3 Changes in Lengths under Uniform Conditions
前情提要 Changes in Lengths under Uniform Conditions [材力小語] 背不出這條公式別說你讀過材力

4 Changes in Lengths under Non-uniform Conditions
第三節 Changes in Lengths under Non-uniform Conditions

5 Changes in Lengths under Non-uniform Conditions
P L Changes in Lengths under Non-uniform Conditions How about this? P L/2 2P A B C

6 Changes in Lengths under Non-uniform Conditions
And, how’s about it !? f (x) P L dx x Changes in Lengths under Non-uniform Conditions f(x) ~ intensity of distributed force [ f ] = F / L, force per unit length

7 Changes in Lengths under Non-uniform Conditions
Now consider an differential element of length dx f (x) P(x) x dx Changes in Lengths under Non-uniform Conditions The elongation of the differential element may be obtained as…

8 Changes in Lengths under Non-uniform Conditions
Now consider an differential element of length dx f (x) P(x) x dx Changes in Lengths under Non-uniform Conditions The elongation of the entire bar is then obtained by integrating over the length

9 Changes in Lengths under Non-uniform Conditions
重點回顧 Changes in Lengths under Non-uniform Conditions [材力小語] 關鍵在於「先切割，再積分」
