In contrast to driving bearing piles for which the direct resistance below the point often becomes greater than the frictional value that the sides can afford, sheet steel piles encounter the greater proportion of their resistance through friction between the ground and their side surface which is very considerable compared with the sectional area of the solid steel pile which can, however, transmit a very high driving force without becoming deformed.

THEORETICAL DISCUSSION. In 1833 Clapeyron stated his law of general work: “For any frame of constant temperature and acted on by loads which are gradually applied, the actual work produced during deformation is independent of the manner in which these loads are created and is always half as great as ths work otherwise produced by forces retaining their full end values during the entire act of deformation.” H.W. Coultas

Niamh McCloskey reflects on her personal experience of the challenging reality of returning to work after maternity leave, questioning whether workplaces truly support women in this transition and highlighting how, with the right support and recognition of the new perspectives and skills that motherhood can bring, we can retain mothers and allow them to thrive in underrepresented industries.
