Preview Questions Chassis Engineer | Role Specific Skill

Question 1: What is the primary function of the shock absorber in a suspension system?

Which action should you take?

Choose only one option

To hold the vehicle's weight and improve handling

To reduce the weight of the suspension system

To adjust the height of the vehicle according to load

To dampen the oscillations of the spring and provide stability

Question 2: In structural analysis, what does the term "stress concentration factor" (SCF) describe?

Which action should you take?

Choose only one option

The distribution of stress across a component

The variation of stress with temperature

The increase in stress around geometric discontinuities

The ratio of maximum stress to average stress in a component

Question 3: In chassis engineering, what is "damping ratio" and why is it important?

Which action should you take?

Choose only one option

It quantifies vibration reduction; important for ride comfort and stability

It represents aerodynamic drag; important for efficiency

It indicates material elasticity; important for strength

It measures the thermal resistance; important for cooling

Question 4: In crashworthiness analysis, which standard is primarily used to evaluate the structural integrity of automotive chassis during collisions?

Which action should you take?

Choose only one option

ISO 26262

ISO 9001

ASTM D638

SAE J2521

Question 5: How does increasing the number of reinforcements in a chassis structure affect its crashworthiness?

Which action should you take?

Choose only one option

It reduces the overall material cost

It improves the energy absorption during a crash

It decreases the structural integrity under load

It increases the weight but reduces the strength

Question 6: How does a suspension's damping force affect vehicle ride comfort and handling?

Which action should you take?

Choose only one option

Damping controls the rate of suspension movement, influencing comfort and handling stability

Damping has no effect on handling

Damping increases the cost of the vehicle without performance benefits

Damping only affects ride height
