Science of the Winter Olympics - The Science of Skis

The video explores the evolution and engineering of skis, highlighting the role of materials like fiberglass and polymers in enhancing performance. It discusses the importance of torsional rigidity, flexibility, and the use of wax to reduce friction. The video also emphasizes continuous innovation in ski technology, drawing parallels to Formula One in terms of testing and tweaking equipment for optimal performance.

What material evolution has significantly impacted ski performance over the past century?

• Transition from wood to metal

• Transition from wood to fiberglass composites

• Transition from metal to plastic

• Transition from plastic to rubber

What is torsional rigidity in the context of ski engineering?

• The ability of a ski to bend without breaking

• The resistance of a ski to twisting forces

• The flexibility of a ski in cold temperatures

• The weight distribution along the ski

Why do slalom racers prefer skis that are less rigid?

• To reduce weight for easier carrying

• To increase speed on straight paths

• To allow better bending during turns

• To enhance grip on icy surfaces

What is the primary function of the polymer coating on modern skis?

• To make the ski waterproof

• To provide a smooth outer surface

• To increase the weight of the ski

• To add color and design

How does wax improve the performance of a ski?

• By enhancing the color of the ski

• By making the ski more flexible

• By reducing friction with the snow

• By increasing the weight of the ski

What role do chemists and material engineers play in ski development?

• Designing ski slopes

• Testing new compounds and polymers

• Coaching ski athletes

• Building ski lifts

What is a polymer in the context of ski materials?

• A fancy name for a plastic

• A type of wax used for ski maintenance

• A type of metal used in ski edges

• A natural fiber used in ski cores
