MOKSHA Quiz Session 1

What is the primary function of the powertrain in a vehicle?

• To improve fuel efficiency

• To control the suspension

• To transfer power from the engine to the wheels

• To provide a comfortable ride

How does a rack and pinion steering system differ from a recirculating ball steering system?

• Rack and pinion system has fewer moving parts

• Rack and pinion system is more complex

• Rack and pinion system is less efficient

• Rack and pinion system provides better feedback to the driver

How does an active suspension system differ from a passive suspension system?

• Active suspension provides a stiffer ride

• Active suspension requires less maintenance

• Active suspension is less expensive

• Active suspension adjusts automatically to road conditions

How does an anti-lock braking system (ABS) work?

• By increasing the pressure in the brake lines

• By adjusting the brake bias between the front and rear brakes

• By preventing the wheels from locking up during braking

• By reducing the friction between the brake pads and the rotors

What is the purpose of a sub-frame in a vehicle's chassis?

• To reduce the vehicle's weight

• To increase the vehicle's speed

• To improve aerodynamics

• To support the weight of the engine and transmission

How does a Finite Element Load Analysis (FEA) help in chassis design?

• By simulating the effects of different loads on the chassis

• By optimizing the vehicle's fuel efficiency

• By improving the vehicle's aerodynamics

• By reducing the vehicle's weight

What is the function of a torque converter in an automatic transmission?

• To change gears automatically

• To transfer power from the engine to the transmission

• To increase the engine's power output

• To improve fuel efficiency

What is the advantage of a power steering system over a manual one?

• Power steering requires less maintenance

• Power steering provides better feedback to the driver

• Power steering is less expensive to manufacture

• Power steering reduces the effort required to steer the vehicle

 How does a camber angle affect a vehicle's handling?

• Positive camber reduces tire wear

• Positive camber improves cornering performance

• Negative camber improves straight-line stability

• Negative camber increases tire contact patch during cornering

What is regenerative braking, and how does it work?

• Regenerative braking improves fuel efficiency

• Regenerative braking uses air resistance to slow down the vehicle

• Regenerative braking converts kinetic energy into electrical energy

• Regenerative braking increases brake pad wear
