Chassis And Suspension System — Part 1 MCQs with Explanations

A tyre that is worn excessively on both edges is most likely caused by underinflation . When a tyre is underinflated, the outer edges of the tread make more contact with the road surface compared to the center, leading to increased wear on both edges. Proper tyre inflation ensures even distribution of the vehicle's weight across the tread, reducing the likelihood of uneven wear.

Torsion bars are a type of suspension component used in vehicles to provide resistance to twisting forces and support the vehicle's weight. They are typically made from various types of steel, including mild steel, treated steel, and high carbon steel. These materials are chosen for their strength, durability, and ability to withstand the torsional loads experienced during vehicle operation. Therefore, the correct answer is that torsion bars can be made from all of the above materials: mild steel, treated steel, and high carbon steel.
