How do planetary gears increase torque?
How do planetary gears increase torque? A planetary gearhead takes a high-speed, low-torque input, say from an electric motor, then increases torque and reduces speed at the output by the gearhead ratio. This lets motors run at higher, more-efficient rpms in equipment that operates at low speeds. Why are there planetary gears? Generally, planetary gears […]
What are the mobile electrons of a pure metal called?
What are the mobile electrons of a pure metal called? The Metallic Bond The electrons in the outer energy levels of a metal are mobile and capable of drifting from one metal atom to another. What metal can withstand 6000 degrees? Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily […]
Why is Venus gravity so strong?
Why is Venus gravity so strong? Since surface pressure is approximately the weight (mass times gravitational acceleration) of the atmosphere divided by the surface area, this means that surface pressure on Venus is very high compared to that of the Earth, by almost a factor of 100. Can humans live Jupiter? Jupiter is made of […]
How visual information is processed in the brain?
How visual information is processed in the brain? Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in […]
What are the ends of a bar magnet called?
Why do chips gain mass in salt solution?
Why do chips gain mass in salt solution? When the chips were put in distilled water they gain mass because the chips gain water from the surrounding solution due to osmosis. The process of osmosis causes a net flow of water across the semi permeable membrane, from a solution with a high water concentration to […]
Do we age in space?
Do we age in space? We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because […]
Does the moon have any satellites?
Does the moon have any satellites? Answer: I believe that there is only one known artificial satellite orbiting the Moon at the moment, that being the Lunar Reconnaissance Orbiter (LRO). The LRO is only about 5 meters in size, which would make it appear to be an unresolved point of light from Earth. What the […]
Can you have a negative velocity and negative acceleration?
Can you have a negative velocity and negative acceleration? An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration). Is friction force negative? So friction is a force […]
