M A = 0 – R BV . L + ½ . q . L 2 = 0<br />

R BV = ½ . q . L = ½ . 10 . 7,071 = 35,355 kN (ke atas)<br />

M B = 0 R AV . L – ½ . q . L 2 = 0<br />

R AV = ½ . q . L = ½ . 10 . 7,071 = 35,355 kN (ke atas)<br />

M S,ki = 0 R AV . ½ L – R AH . H – ½ . q . (½ L) 2 = 0<br />

R AH = (R AV . ½ L – ½ . q . (½ L) 2 / H = 42,676 kN (ke kanan)<br />

M S,ka = 0 R BH . H – R BV . ½ L + ½ . q . (½ L) 2 = 0<br />

R BH = (R BV . ½ L – ½ . q . (½ L) 2 / H = 42,676 kN (ke kiri)<br />

Kontrol:<br />

F H = 0 R AH – R BH = 42,676 - 42,676 = 0 OK!<br />

F V = 0 R AV + R BV – q . L = 35,355 + 35,355 – 10 . 7,071 = 0 OK!
