Perhitungan Momen Eksternal

Untuk Perhitungan Momen Eksternal didapat dari hasil pengujian yang dalam hal ini nilai momennya didapat dengan cara statika biasa.

Diketahui data Balok BLPI-1

P= 1350 kg = 13230,898 N

L = 210 cm = 2100 mm

RA = RB = P/2 = 66217,5 N

Didapat :

M= RA x (L/3)

= 66217,5 N x 2100 mm

= 4630814 N mm

Momen Inersia (I) =

=

= 8359189,18 mm4
