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 […]
Is 40 degrees hot for a hot tub?
Is 40 degrees hot for a hot tub? However, 40°C is the highest safe hot tub temperature and is the industry agreed maximum, with BISHTA stating that bathing in water exceeding 40°C is potentially harmful and should be avoided. Most hot tubs factory settings will be set at 38°C, which is 1 degree higher than […]
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 does healthy living mean to you?
What does healthy living mean to you? ‘Healthy living’ means maintaining a healthy lifestyle and introducing habits that improve your health. It can be difficult to change old habits, but there are steps you can take to become healthier. Why good health is important? Being healthy should be part of your overall lifestyle. Living a […]
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 […]
What was life like during the Paleozoic Era?
What was life like during the Paleozoic Era? By the end of the Paleozoic, cycads, glossopterids, primitive conifers, and ferns were spreading across the landscape. The Permian extinction, 244 million years ago, devastated the marine biota: tabulate and rugose corals, blastoid echinoderms, graptolites, and most crinoids died out, as did the last of the trilobites. […]
Does the mass of the satellite have any impact on its orbit?
Does the mass of the satellite have any impact on its orbit? The mass of the satellite definitely affects where it stays in the orbit (leo, meo or geo). Gravitational force between two objects is directly proportional to the product of their masses and indirectly proportional to the square of the distance between them. Does […]
What are 3 characteristics of cyanobacteria?
What are 3 characteristics of cyanobacteria? Defining cyanobacteria characteristics are a tolerance of extreme conditions and an ability to exist without vitamins. They use phosphorus, iron and other micronutrients, and ammonia or nitrate as a nitrogen supply. Some types of cyanobacteria are filamentous and don’t need sunlight. What does cyanobacteria do to humans? Exposure can […]
What are the two rules of refraction?
Can be drawn into thin wires?
Can be drawn into thin wires? ductile: A material that can be drawn into wires. malleable: Means that the material can be hammered into very thin sheets without breaking. metal: An element that is a good conductor of heat and electricity. What are the two properties that make metals a good choice to use as […]
