M A = 0<br />
M x = A H . x – ½ q . x 2<br />
M mak � dMx/dx = 0 � x = 3,75 / 1 = 3,75 m<br />
M mak = 3,75 . 3,75 – ½.1.3,75 2 = 7,03125 tm<br />
M tengah = 3,75 . 2,5 – ½.1.2,5 2 = 6,25 tm<br />
M C = M x=5 m = 3,75 . 5 – ½.1.5 2 = 6,25 tm<br />
Pada Batang CD<br />
M x = A H . 5 – q . 5. 2,5 –A V . x = 3,75 . 5 – 5 . 2,5 – 1,25 . x = 6,25 – 1,25x<br />
M x=0 = M C = 6,25 – 1.25.0 = 6,25 tm<br />
M x=5 = M S = 6,25 – 1,25 . 5 = 0 tm<br />
M x=10 = M D = 6,25 – 1,25 . 10 = -6,25 tm<br />
Pada batang BD<br />
