Unformatted text preview: • Calculate the normal force on the left side tires ( N L ) and right side tires ( N R ) as the Ranger goes around a flat lefthand curve (no banking or superelevation) of radius r C =350 feet at speeds of v=30 mph and v=60 mph . • Determine the speed at which the Ranger is just about to start a rollover, i.e., N L = 0. What coefficient of friction is required for a rollover to occur ( μ = F R /N R )? 3. An aluminum plate with 8 steel cylinders is arranged as shown. Determine the mass moment of inertia about the Z axis at the center of mass of the entire system . Express I G in units of lbfftsec 2 and kgm 2 .
