Steering Geometry 1

1)

Caster: 5.38 deg

Mechanical trail: 9.41mm

kingpin inclination angle: 10.01 deg

scrub radius: 32.35mm

kingpin lateral offset: 85.29mm

2)

Pneumatic trail: 25mm

mechanical trail: 9.41mm

lateral force: 2000N

Restoring moment: lateral force (PT+MT)

= 2000(25+9.41)

= 68820 N-mm

3)

we can make scrub radius zero by reducing the kingpin lateral offset by 35.29mm and if we reduce it than scrub radius would become negative.
