1. A pipe 1 metre in diameter, buried in a trench 1.4 m wide, is backfilled with dry sand. The top of the pipe is 2.5. m below the surface of the fill. The pipe passes at right angles under a one lane road which carries a vehicle whose loading (including impact) consists of two concentrated 800 kg loads located at 1.8 m apart transverse to the roadway. Find the maximum vertical force exerted on a unit length of the pipe, if (a) the pipe is made of steel. (b) the pipe is a cast iron pipe. The thickness of the pipe may be neglected for calculating the external dia of the pipe. (c) what is the stress produced in steel pipe, if its thickness is 1 cm?
