Your car has a suspension geometry with zero caster, camber and toe. The tire contact path is assumed to be linear, the contact force distribution is assumed to be triangular (see image). How much steering torque applied on the steering wheel is required to move the steering from the center postion during standstill? Tire width w: 7 inch Control rod arm e: 95mm Pinion meshing diameter d: 34mm Weight of car /w driver 272kg Weight distrubution /w driver: 48% Rear Static tire µ: 1.5 (CoF) g= 9.81 m/s² Answer in [Nm] rounded to .1

Top-view schematic of one wheel/tire and its steering linkage. A vertical rounded tire outline on the left has width marked "w" by a horizontal double-headed dimension arrow; a dotted vertical centerline passes through it. Two linkage connection marks near the wheel center are separated by a vertical offset labeled "e". Gray angled suspension/control arms extend to the right. A long horizontal narrow steering rack with teeth connects to a small toothed pinion at upper right; its diameter is indicated by "d". A black steering shaft runs down to a steering-wheel symbol with a red curved rotation arrow. At right, inset "Tire load distribution" shows a triangular red-hatched pressure distribution across the tire width, and "Tire contact patch" shows a horizontal red line under the tire outline. No numeric dimensions appear.
