Steering Geometry 1
Answer 1.i. Caster angle: 5.38o
Answer 1.ii. Mechanical trail: 9.41 mm
Answer 1.iii. Kingpin inclination angle: 10.01o
Answer 1.iv. Scrub radius: 32.35 mm
Answer 1.v. Kingpin lateral offset or spindle length: 85.29 mm
Answer 2. Restoring moment= Moment arm* Lateral force
= (Pneumatic trail + Mechanical trail) * Lateral force
= (25 + 9.41) * 2000
= 68820 Nmm
Answer 3. We can change the value of scrub radius by moving LCA_Knuckle_Ball_Joint outward (towards wheel side) or by moving UCA_Knuckle_Ball_Joint inward (away from wheel) or by both.
