7.7 A contractor wants to explore using a 7U blade on a 240 hp dozer. The material is a dry, noncohesive silty sand and must be moved a distance of 200 ft from the beginning of the cut. It is estimated the material will swell 4%, from bank to loose state. Both visibility and traction should be satisfactory. Job efficiency is assumed to be equivalent to a 50-min hour. The U-blade width is 13 ft 1 in with 3.25 ft...

A piston/cylinder arrangement with an cross sectional area of 1 mạ contains carbon dioxide at 200 kPa and 290 K. The cylinder has a thick piston that initially held by a pin as shown in Figure 1. The metal piston has a density of 8000 kg/mº, standard acceleration of gravity, &c is 9.81 m/s and the atmospheric pressure is 101 kPa. The pin is now removed, allowing the piston to move and after a while the gas returns to 290...
