A construction vehicle has a diesel engine with eight cylinders of 5.735-inch bore and 8.0-inch stroke, operating on a four-stroke cycle. It delivers 161-shaft horsepower at 1000 RPM, with a mechanical efficiency of 0.60. Calculate: (3.1) Total engine displacement in litters & Torque at 1600 RPM. [lbf-ft].  (3.2) Indicated horsepower & Friction horsepower

11 Sunco Oil has refineries in Los Angeles and Chicago.The Los Angeles refinery can refine up to 2 million barrelsof oil per year, and the Chicago refinery up to 3 million.Once refined, oil is shipped to two distribution points:Houston and New York City. Sunco estimates that eachdistribution point can sell up to 5 million barrels per year.Because of differences in shipping and refining costs, theprofit earned (in dollars) per million barrels of oil shippeddepends on where the oil was refined and on the point ofdistribution (see Table 51). Sunco is considering expandingthe capacity of each refinery. Each million barrels of annualrefining capacity that is added will cost $120,000 for the LosAngeles refinery and $150,000 for the Chicago refinery. Uselinear programming to determine how Sunco can maximizeits profits less expansion costs over a ten-year period.

You design a gearbox with a gear ratio of 5 (GR=5=TGB/Tm) to pull a load (FL) of 76 lbf using a motor and winch (rw=0.25 inches). What is the torque experienced by your motor when pulling the mass up at a constant speed in lbf ft? Note the units
