1. Properties of Beams
To understand the properties of the beam, try to look at the following picture of the beam!
a. The beam has six sides, namely:
- base side : ABCD - top side : EFGH
- front side : ABFE
- back side : DCGH
- right side : BCGF
- left side : ADHE
b. The beam has eight corner points, namely:
point: A, B, C, D, E, F, G, H.
c. The beam has twelve ribs, namely:
- base ribs: AB, BC, CD, DA
- upright ribs: AE, BF, CG, DH
- upper ribs: EF, FG, GH, HE
d. The beam has three groups of ribs that are the same length, namely:
- rib AB = DC = EF = HG
- ribs AD = BC = FG, EH
- ribs AE = BF = CG = DH
e. The beam has parallel ribs (//), namely:
- rib AB // DC // EF // HG - rib AD // BC // FG // EH
- ribs AE // BF // CG // DH
f. The beam has three pairs of parallel sides, namely:
- ABCD side // EFGH
- ABFE side // DCGH
- ADHE side // BCGF
