ʻO nā mea hoʻohui angular a i ʻole nā ​​ʻāpana kihi nā mea hoʻohui kumu no nā pilina keʻa perpendicular (90⁰). Hiki iā lākou ke hana ma ke ʻano he kākoʻo no nā pilina beam-pole. Hoʻopau maʻalahi ʻia lākou e hiki ai ke hoʻopili ʻia i loko a ma waho o ka pilina. Hoʻokomo pū ʻia ka laulā huahana i nā ʻāpana kihi i hoʻoikaika ʻia e hōʻike ana i ka ikaika flexural i hoʻonui ʻia. ʻO ka loaʻa ʻana o nā puka ʻano pī i maʻalahi i ka hoʻopaʻa ʻana i nā mea unorthodox a me ka hoʻopau ʻana i nā pilikia dilatation.
