Abstract
The yieldable load support comprises a compressible support member in the form of an elongate timber pole. The load support or pole is asymmetrically modified at or near one end thereof in a manner to positively induce sideways brushing of the pole at the modified end, in a preferential direction transverse to the length of the pole, when the support member is placed under longitudinal compressive load of sufficient magnitude.
