Motion Ratio or Installation Ratio in Suspension Solution

Follow our step by step solution on how to calculate Motion Ratio or Installation Ratio in Suspension?

FIRST Step Consider the formula

M.R. = \frac{ST}{WT}

Next Step Substitute values of Variables

∴

M.R. = \frac{65mm}{100mm}

Next Step Convert Units

∴

M.R. = \frac{0.065m}{0.1m}

Next Step Prepare to Evaluate

∴

M.R. = \frac{0.065}{0.1}

LAST Step Evaluate

∴

M.R. = 0.65

Go Angle of Outside Wheel Lock Satisfying Correct Steering Condition

θ out = a \cot (\cot (θ in) + \frac{c}{L})

Go Angle of Inside Wheel Lock Satisfying Correct Steering Condition

θ in = a \cot (\cot (θ out) - \frac{c}{L})

Go Angle of Inside Lock given Turning Radius of Inner Front Wheel

θ in = a \sin (\frac{L}{R IF + \frac{a tw - c}{2}})

Go Angle of Outside Lock given Turning Radius of Outer Front Wheel

θ out = a \sin (\frac{L}{R OF - \frac{a tw - c}{2}})
