Unformatted text preview: b) Plot the Fx (N-m) curves verses velocity (m/sec) on a single graph for the four gears. c) Assume zero drive-train inertia; find the optimum shift points in rads/sec and RPM. d) What is the minimum 0 to 60 m/sec time with zero drive-train inertia? e) Assume that the engine inertia is 2kg-m 2 and that there is zero inertia for the remaining rotating components. What is Mr (kg) for the 4 gear ratios? f) What are the optimum shift points when Mr is taken into consideration? g) What is the minimum 0 to 60 m/sec time when the engine inertia is modeled? (When shifting up, assume that the engine drops speed instantaneously without a torque impulse to the drive-train.)...
