Fiberglass is lighter, AND stronger.
You would be lighter in space because weight is the result of gravity pulling on your mass. In the absence of gravity in space, you would not experience the same force pulling you down, making you feel weightless.
Your weight will always differ depending on the pull of gravity to which you are experiencing. Your mass however, will not change. So for instance, the force of gravity on the moon is 1.635 m/s2 whereas the force of gravity on earth is 9.81m/s2 therefore the weight would be different. You can find your mass and weight doing simple physics calculations.
A rock's weight on the Moon would be about one-sixth of its weight on Earth due to the Moon's lower gravitational pull. Conversely, on the Sun, the rock would weigh significantly more—approximately 27 times its weight on Earth—because of the Sun's much stronger gravity. Thus, while a rock would be lighter on the Moon, it would be substantially heavier on the Sun.
If you took an object to the moon, its weight would decrease significantly because the moon's gravitational pull is only about one-sixth that of Earth's. While the object's mass remains the same, its weight—defined as the force exerted by gravity on that mass—would be much lighter on the moon. This means the object would be easier to lift and move compared to its weight on Earth.
Your MASS (kg) is always the same not matter what the force of gravity. Your WEIGHT (N) however is different as the gravity of whatever planet has an effect on each atom making it heavier or lighter. To answer your question, only your weght would be lighter on the moon.
lighter
since it is really hot in central africa, you would need lighter clothing there.
One of Mars's moons? Yes, yes you would be "lighter" (as in less weight) due to titan only being a few miles wide
The oil light is turning on BECAUSE you put in the lighter weight oil. older engines need the thicker oil.
There is no definite temperature that plywood would combust at. Since plywood contains various chemicals, it will depend on what type those are, its size, etc.
Carbon fiber would be lighter than the same structural rigidity in aluminum
Aluminum would be lighter weight than stainless steel.
Plywood. It has more trapped air.
It depends on theplywood density if it is denser then water then you would have to make a shape causing it to displace an equal or greater amount of water in weight for it to float.
CDX plywood is made from multiple layers of wood veneer and is commonly used for construction projects due to its durability and strength. RTD plywood, on the other hand, is made from a single layer of wood veneer and is known for its smooth surface finish. The choice between CDX and RTD plywood depends on the specific requirements of your project. If you need a strong and sturdy material for structural purposes, CDX plywood would be the better option. However, if you prioritize a smooth and aesthetically pleasing finish, RTD plywood may be more suitable.
It depends on the density of the plywood. This site shows some plywood densities in kg/m^3. Let's say your plywood is 500 kg/m^3 (which is at the low end of the plywood densities isted on that page). Converting the dimensions of the plywood to meters gives the following: height: 4 ft = 4 ft * (12 in/ft) * (2.54 cm/in) * (1m/100cm) = 1.22 m width: 8 ft = 8 ft * (12 in/ft) * (2.54 cm/in) * (1m/100cm) = 2.44 m thickness: 18 mm * (1m/1000mm) = .018 m The volume of the plywood is height * weight * thickness = 1.22 * 2.44 * .018 = .0535 m^3. Weight is density * volume. So, at 500 kg/m^3, the plywood would weigh: 500*.0535 = 26.8 kg. 1 kg is approximately 2.2 pounds, so 26.8 kg is 26.8 kg * (2.2 lb/kg) = 58.9 pounds. If, however for example, your plywood is 700 kg/m^3, it would weigh 40% more, or 82.5 pounds.
I would buy some new plywood You will be able to bad plywood thru the shingles... especially 20 year shingles.
