Quiz Test 1

Which of the following statements is NOT a reason for the inclusion of lift systems in modern building design?

• The rapid increase in land prices has encouraged vertical construction.
• Lifts provide comfort and improve working efficiency in large office buildings.
• Lifts are installed purely for aesthetic appeal in high-rise buildings.
• The Unified Building Bye-laws (UBBL) require lifts in buildings with more than 6 storeys

What is the working principle of a hydraulic elevator?

• It uses gears to rotate a pulley system
• It uses a hydraulic ram pushed by pressurized fluid to lift the elevator car
• It relies on a vacuum system to lift the car
• It uses magnetic levitation for movement

How does the elevator car rise in a hydraulic elevator system?

• The car is pulled up by a motor at the top of the shaft
• A cable system rotates to move the car
• The piston moves up as hydraulic fluid is pumped into a sealed cylinder
• Air is compressed beneath the elevator car

Where are hydraulic elevators commonly used?

• Skyscrapers and towers
• Offices, hospitals, apartments, and shopping centers
• Industrial plants only
• Underground mines

Which of the following is NOT an advantage of hydraulic elevators?

• Energy efficiency
• Quiet and smooth movement
• High-speed travel in tall buildings
• Cost-effective installation

Why are hydraulic elevators not suitable for very tall buildings?

• They are too expensive
• They consume too much energy
• They have height limitations and slower speeds
• They require constant maintenance

What is the working principle of a traction lift?

• Hydraulic pressure
• Magnetic levitation
• See-saw mechanism with counterweights and ropes
• Pneumatic suction system

How does a traction lift move the elevator car?

• By pushing from below with a piston
• By pulling with steel ropes and a counterweight
• By using compressed air
• By rotating a central drum

Where is the operating machinery typically located in a traction lift system?

• At the basement of the building
• In a side room next to the shaft
• Above the elevator hoist way
• Beneath the elevator car

Traction lifts are most suitable for:

• Medium and high-rise buildings
• Low-rise buildings only
• Underground transportation systems
• Small residential homes
