[閒聊] 紓發讀書壓力或與板友互動,勿濫用此選項挑釁、引戰,或漫無
邊際用此選項發文。
剛好有抄計算題的答案回來, 跟大家對一下吧~
一、力學 :
Q2: 1) 摩擦力f在0~3.5s時, 與F對稱於時間軸, 3.5~4s(大小由300N垂直降到200N水平線)
2) 3.5~4s a=10(等速), 速度斜直線, 位移二次曲線 瘦到胖(V4=多少我忘了抄)
Q3: 功能原理 W12 = T12, 當位能最小時,動能最大, 即 V_max = 3.189 m/s
(奇怪,我也是寫在D的正上方時,會有最小位能,但是答案怎麼.)
Q4: d > 119.9 mm (d_AB = 115 ; d_BC = 96.97 ; d_饒角 = 119.9 mm)
= (剛剛從算的)
2
P * L
Q5: 1) sita = ------------
32 * E * I
3
5 * P * L
2) 位移 = ------------
576 * E * I
二、機設
Q1: 1) Ns = 2.23
2) Ns = 7.76
Q2: 3) d = 0.45 m
Q3: 1) w = 2.9 mm
2) h = 7.855 mm
I
Q4: 1) ( --- + 2rm ) x'' + kr*x = 2mgr
2r
2) wn = [(2kr^2) / (I + 4mr^2)]^0.5
三、熱力
Q1: 0.22175 (應該不對)
Q2: 1) 焓差值 = 1487.43 KJ
QH = 1062.45 KJ
o
2) 45.65 C
Q3: 1) w_out,s = 430.8 KJ/kg
w_out,a = 387.72
2) h_f@60kpa < h2,a < h_g@60kpa
==> 仍處於飽和狀態
Q4: 熱效率 = 60.37 %
剩下自控與流力我是真的沒把握了
如果答案有錯~ 懇請高手指正 感激!
