1. 請問不計橫桿重量時，柱子受力為何？ 2. 加計橫桿自身重量為 10kg 時，柱子受力又為何？ 謝謝大家～
物理力學的問題，求解...?

(1) F = ? if column length = L
M = 50 * 0.75 = 37.5 kg.m
F = -50*j + M/L * i = -50*j + 37.5/L * i kg if built-in
(2) F1 = ?
= (50*0.75 + 10*0.375)/L
= 41.25/L kg
F2 = -60*j + 41.25/L * i if built-in
M = 50 * 0.75 = 37.5 kg.m
F = -50*j + M/L * i = -50*j + 37.5/L * i kg if built-in
(2) F1 = ?
= (50*0.75 + 10*0.375)/L
= 41.25/L kg
F2 = -60*j + 41.25/L * i if built-in

理論上柱子的受力好像遠大於吊重的樣子。ㄎㄎ
