The image represents a reaction at the inner wheel of a vehicle moving along a level circular path. To calculate the reaction, six essential parameters are needed and these parameters are **Mass of the Vechicle (m), Acceleration due to Gravity (g), Velocity of the Vehicle (v), Height of Centre of Gravity of the Vehicle from Ground Level (h), Radius of Circular Path (r) and Half of the Distance between the Centre Lines of the Wheel (a).**

The formula for calculating the reaction at the inner wheel of a vehicle moving along a level circular path:

R_{A}Â =Â ^{mg} / _{2}[1 –Â ^{vÂ²h} / _{gra}]

Where:

R_{A}Â = Reaction at the Inner Wheel of a Vehicle moving along a Level Circular Path

m = Mass of the Vechicle

g = Acceleration due to Gravity

v = Velocity of the Vehicle

h = Height of Centre of Gravity of the Vehicle from Ground Level

r = Radius of Circular Path

a = Half of the Distance between the Centre Lines of the Wheel

**Let’s solve an example;**

Find the reaction when Mass of the Vechicle (m) is 13, Acceleration due to Gravity (g) is 9.8, Velocity of the Vehicle (v) is 11, Height of Centre of Gravity of the Vehicle from Ground Level (h) is 5, Radius of Circular Path (r) is 7 and Half of the Distance between the Centre Lines of the Wheel (a) is 3.

This implies that;

m = Mass of the Vechicle = 13

g = Acceleration due to Gravity = 9.8

v = Velocity of the Vehicle = 11

h = Height of Centre of Gravity of the Vehicle from Ground Level = 5

r = Radius of Circular Path = 7

a = Half of the Distance between the Centre Lines of the Wheel = 3

R_{A}Â =Â ^{mg} / _{2}[1 –Â ^{vÂ²h} / _{gra}]

RA = ^{13(9.8)} / _{2}[1 – ^{(11)Â²(5)} / _{(9.8)(7)(3)}]

That is, RA = ^{127.4} / _{2}[1 – ^{(121)(5)} / _{205.8}]

RA = 63.7[1 – ^{605} / _{205.8}]

RA = 63.7[1 – 2.939]

Then, RA = 63.7[-1.939]

RA = -123.56

Therefore, the **reaction at the inner wheel of a vehicle moving along a level of circular path** is **-123.56 N.**
