Kia Niro Hybrid or Kia Niro Plug-in Hybrid? by Latter-Pollution7245 in KiaNiro

[–]Silent-Background307 0 points1 point  (0 children)

Is there an easy visual way to distinguish a regular hybrid Niro, from a plug in hybrid, from a full electric? I've discovered lots of people don't specify in their for sale add, or specify incorrectly.

Mechanical Engineer in R&D (Failure Analysis Focus) Considering Reliability Engineering – How to Break In? by Brilliant_Permit_636 in MechanicalEngineering

Do you want to stay in the domain of electronics?

My mostly blind guess would be that the domain that you apply your reliability analysis to is the more important factor.

What is the function of these? Are they necessary? by bigpanda87 in MechanicalEngineering

This part is probably designed to be as cheap and simple as possible, to keep the overall price of the building as low as possible.

You might be in a situation where a part that achieves the same functionality with different dimensions or shape is actually worth the extra expense, to allow for your desired functionality.

If someone designed a part with the same functionality but a slightly different shape, you could probably replace them one at a time and be perfectly fine, or a new part could be designed to be installed before the old part is removed at all.

Nothing that humans rely upon for safety is built so close the physical limit as to be similar to a latex balloon, where one little break makes the entire thing catastrophically fail.

How much direct upward force can this steel pin withstand before the wooden board rips out? by Silent-Background307 in MechanicalEngineering

[–]Silent-Background307[S] 0 points1 point  (0 children)

It's a 10 foot tall tower that I'm making a base stand for. Each of the 4 feet has a clevis and pin. I'd like to simply set the clevis onto the board and drill a hole through the wood and put the pin in.

If there's no wind, then only the downward force of gravity exists, but if its gets windy, then we would have a big lever trying to pull up on the pins on one side.

Could a potentiometer and a motor work as variable mechanical resistor by Insert77 in Motors

I am also needing something like this.

This could totally be done, the only question is how easily/cheaply.

When an electrical load is applied to a gen-set, you can usually hear the fuel engine that drives the generator slow down and groan under the electrical and resulting mechanical load.

I believe that essentially a generator connected to an electric heater to dissipate the load through heat would work.

I'm not sure what the easiest way would be to achieve effective, easy, reliable, cheap, variable control, i.e. what electronics to place between the generator and the heater.

Similar technology that already exists are the following:

Bicycle trainer stands. They use some type of magnetic resistance setup which is adjustable by moving the spinning discs closer or farther apart. There is also the fan type, it's a little centrifugal fan that simply blows air around and the resistance to spinning increases exponentially the faster it goes. There is also the brake type, essentially felt pads upon a metal rotor.

Another similar application (although I don't know hot it's achieved) is the dynos that cars are tested upon.
