Beam subjected to moment load はりの応力とSFD,BMD 基本例題4.21 P99 「材料力学演習(20221021)」をsympyでやってみたい。

Last updated at Posted at 2025-01-05

モーメント荷重が作用するはり(端部)

オリジナル

基本例題4.21 P99「材料力学演習(20221021)一括(ver.3.3)」を勉強したい。#sympy
???タブレット等で、pdfを開く事ができないかも。??? 

sympyで

・ver0.1

# ver0.1
# 基本例題4.21 P99
from sympy import *
var('MC,l,x,RB',real=True)
F =(MC/l).subs({MC:1000,l:1})     ;print("#",F)
RA=F
M =RA*x                           ;print("#",M)
print()
F =(MC/l).subs({MC:1000,l:1})     ;print("#",F)
RA=F
M =(RA*x-MC).subs({RA:F,MC:1000}) ;print("#",M)
RB=solve(Eq(RA+RB,0),RB)[0]       ;print("#",RB)
# 1000
# 1000*x

# 1000
# 1000*x - 1000
# -1000

いつもの? sympyの実行環境と 参考のおすすめです。

(テンプレート)

いつもと違うおすすめです。
