R=K/i~/2)) ^rid ^^ ^ gives the direction of pi, the unit of pressurebeing the weight of one cubic foot of earth. The principal stresses are now known and the pressure on the backof the wall can be found. To find the pressure on O B at O, drawO A parallel to M X and O M normal to the back of the… … drawing and multiplied by the weight of a cubic foot of earth, givesthe pressure in pounds per square foot at O. As the pressure on the back increases regularly with the distancebelow the surface of the ground, the centre of pressure will be at D,one-third of the slant height from O, and the total…
