What is the primary advantage of using aluminum for boat construction?

• It is the most affordable metal

• It is lightweight and resistant to corrosion

• It is easy to weld

• It has superior strength compared to steel

Which type of steel is most commonly used in boat building for its ability to withstand harsh marine environments?

• Mild steel (stal miękka)

• Stainless steel (stal nierdzewna)

• Carbon steel (stal węglowa)

• Tool steel (stal narzędziowa)

Cupronickel alloys (stopy miedzioniklu), often used in boat building, are primarily made from copper (miedź) and which other metal?

• Zinc (cynku)

• Nickel (niklu)

• Iron (żelaza)

• Manganese (manganu)

Which of the following is a key feature of ferrocement construction in boats?

• Lightweight composite material

• Concrete reinforcement with wire mesh or steel rods

• Made from synthetic resin and fiberglass layers

• Mainly used for high-speed racing boats

What is one major advantage of using fiberglass for boat construction over traditional wooden boats?

• Higher resistance to rot and decay

• Easier to repair

• More affordable to produce (bardziej przystępne cenowo do wyprodukowania)

• Better fuel efficiency (niższe zużycie paliwa/lepsza wydejność paliwa)

Which wood is often used for the hull of luxury yachts due to its strength, density, and water resistance?

• Mahogany

• Cedar

• Pine

• Birch (brzoza)

What is a common disadvantage of using steel for boat hulls?

• High cost of material

• Susceptibility to corrosion if not properly maintained (Podatność na korozję, jeśli nie jest odpowiednio konserwowana)

• Heavier than other metals like aluminum

• Difficult to fabricate (trudny do wyprodukowania)

Which of the following is a key difference between aluminum and steel when used in boat building?

• Aluminum is more corrosion-resistant than steel, especially in saltwater

• Steel is lighter than aluminum

• Aluminum boats are more prone to cracking under stress than steel boats (Łodzie aluminiowe są bardziej podatne na pękanie pod wpływem naprężeń niż łodzie stalowe)

• Steel boats require less maintenance than aluminum boats (Łodzie stalowe wymagają mniej konserwacji niż łodzie aluminiowe)

Why is ferrocement a popular choice for constructing large, durable boats, particularly in developing regions?

• It is lightweight and easy to transport

• It requires advanced skills and tools to build

• It is affordable, uses locally available materials, and can be built with minimal technology

• It has the highest performance speed potential (Ma najwyższy potencjał prędkości działania)
