Explain the necessity of anti roll bar in automobile with justification.
Necessity- Antiroll bar is used to reduce the tendency of the vehicle to roll on either side when taking a turn.
Justification- When both the wheels deflect up and down by the same amount, the stabilizer bar simply turns in the bearings. When only one wheel deflects, then only one end of the stabilizer bar moves, thus twisting the stabilizer bar which acts as a spring between the two sides of the independent suspension.
