MENGHITUNG REAKSI PERLETAKAN DAN MOMEN; SIMPLE BEAM

 

Hitung Momen di Masing-masing Titik !!!

Penyelesaian:

• ∑MA=0

BV = 

P1.3 + P2.6 - BV.9 = 0

10.3 + 10.6 + BV.9 = 0

30 + 60 - BV.9 = 0

90 - BV.9 = 0

-BV.9 = - 90

BV= 90/9 = 10 Ton

• ∑MB = 0

AV=

AV.9 - P1.6 - P2.3 = 0

AV.9 - 10.6 - 10.3 = 0

AV.9 - 60 - 30 = 0

AV.9 - 90 = 0

AV = 90/9 = 10 Ton

Menghitung Momen dititik C dan D

• Momen dititik C

∑MC = AV.3

∑MC = 10 Ton . 3 Meter

∑MC = 30 TonMeter

• Momen dititik D

∑MD = AV.6 - P1.3

∑MD = 10 Ton.6 Meter - 10 Ton.3 Meter

∑MD = 60 TonMeter - 30 TonMeter

∑MD = 30 TonMeter

• Rekapitulasi Hasil

∑MA = 0 (Sendi)

∑MB = 0 (Roll)

∑MC = 30 TonMeter

∑MD = 30 TonMeter
