applied stress of 240 kPa on the ground surface. Between the depths of 21 and 27 m there is a layer of soft clay. The rest of the subsoil is dense sand. Compute the applied vertical pressure due to the weight of the building, at the following points located in a horizontal plane at mid-height of the compressible layer: directly below centerline of building; and 6, 12 and 18 m from the centerline.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
