- = A steel pile (H-section; HP 310 x 125; and so A, 15.9 x 10-3 m² ) is driven into a layer of sandstone. The length of the pile is 25 m. Following are the properties of the sandstone: unconfined compression strength = qu(lab) = 78 MN/m² and angle of friction = 36°. Using a factor of safety of 3, estimate the allowable point load that can be carried by the pile. Use [qu(d Qu(lab). qu(design) b)/5]. (Enter your answer to three significant figures.)
