Textbook Question
Chapter 12, Problem 12.18P
A steel pile (H-section; HP 310 × 125; see Table 12.1a) 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) = 80 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(design) = qu(lab)/5].

P.3.3
Oil of sp.gr. 0.9 flows through a vertical pipe (upwards). Two points A and B one
above the other 40 cm apart in a pipe are connected by a U-tube carrying mercury. If
the difference of pressure between A and B is 0.2 kg/cm²,
1- Find the reading of the manometer.
2- If the oil flows through a horizontal pipe, find the reading in manometer for the
same difference in pressure between A and B.
