Challenge

Steering Geometry 1

Caster = 5.37 deg

Mechanical trail = 9.411 mm

Kingpin inclination angle = 10.00 deg

Scrub radius = 32.352 mm

Kingpin lateral offset or spindle length = 14.7058 mm

2. Given,

pneumatic_trail = 25 mm,

lateral_force = 2000 N.

From the calculations, we got mechanical_trail as 9.411 mm.

restoring_moment = (mech_trail+pneuma_trail)*lateral_force

= (9.411+25)*2000

restoring_moment = 68822 N-mm

3. Changing LCA_KNUCKLE_JOINT to -777 on Y-axis changes the sign of Scrub Radius
