“What opposes electric current flow?”
Resistors are commonly known to oppose electricity. However, how can other components such as capacitors and transducers oppose it as well? Well, it turns out that each of these components contribute to something called the Electrical Reactance of the system. Due to the time-varying nature of the components, reactance is typically used when dealing with AC signals.
Bicycle Gear Ratios
“How does the gear ratio on a bicycle work?”
Everyone who’s had a bicycle has probably had to deal with gear ratios. But what exactly are they and how exactly do they work? Well, put simply, the gear ratio is the ratio between one pedal turn and one wheel turn. So if you have a gear ratio of 2-1, then your bicycle’s wheel will make two complete revolutions with one full revolution of the pedal. As a result, when you are going uphill, you should shift into low gear, since you will then not have to use as much force when pedaling.
Why Los Angeles is Painting its Streets White
“Why is the City of Angels painting its streets white?”
Something very exciting and innovative is happening right now in my hometown of Los Angeles. To combat climate change, the city is starting to paint some of its streets white. Since the lighter color will reflect more sunlight, less heat will be trapped on the streets, causing local temperature levels to drop up to 10 degrees Fahrenheit (5.5 degrees Celsius) and lessening the need for energy-intensive HVAC systems!
“How can we control processes?”
Industrial processes are at the heart of the industrial internet of things. However, in order to ensure that the process is going in accordance with the procedure, there must be some form of guidance. For that reason, engineers have developed something known as Process Control, which allows a systems process to stay within all setpoints.
Flexible Solar Conduits
“How can we have solar conduits that can easily bend?”
Conduits are vital for protecting solar wiring. However, sometimes we may need them to make tight and sudden bends. That’s why engineers have created Flexible Solar Conduits, which can allow for great maneuverability.
Rigid Solar Conduits
“What type of solar conduits do we use when we need extra strong support?”
Solar Conduits are vital for keeping solar infrastructure alive. However, sometimes we need to have extra support. That’s where Rigid Solar Conduits come in. Although they are better for longer or runs, their extra strength makes it more difficult to integrate with bends and turns.
“How can we guard solar wires against hazards?”
Wires are like the blood vessels for solar energy. And as such, any damage to them can be catastrophic to the system. As a result, they need to have some form of protection. This often comes in the form of solar conduits, or a material layer that shields the wires from all external elements.
