a) If the steady-state roll angle is given by the following equation: \theta=\frac{m v^{2}\left(a_{F} d+a_{R} c\right)}{R L\left(\frac{k_{p} t^{2}}{2}+\frac{k_{B} t^{2}}{2}-\frac{W}{L}\left(a_{p} d+a_{R} c\right)\right)} Simplify the equation for the case when the roll

axis is on the ground and comment on the significance of the center of gravity height, h, for such a case. b) Calculate the body roll is in the given driving condition. c) What simplifications have you made in this condition? d) With the ald of suitable sketches, describe Double Wishbone system. e) Provide four reasons why rigid axles are not generally used in motor sportapplications. What are the (well-known) exceptions? A test driver comes into the pits complaining about understeer on corner entry. What is the issue and what adjustments to toe and camber are necessary to counteract this tendency?
