I cannot be 100% certain that the centrifugal switch on my table-saw motor is bad, but here are some symptoms that I recently experienced: 1) The motor starts fine, but the motor-start capacitor begins smoking (bad sign) while the motor is running. I think this means the switch is sticking closed in this case. 2) Other times, the motor does not want to start at all. If I slacken the drive belt, the motor starts spinning. When it gets up to speed, I can tighten the belt and go ahead and use the saw. In this case, I think the switch is sticking open. I first experienced symptom #1, which led me to believe I had a bad capacitor. I replaced it, but after a few uses, the new capacitor also smoked. Then I noticed symptom #2. After doing a little web snooping, I have nearly concluded that the problem is the centrifugal switch. Just not sure yet how to get to it or find a replacement. . . Bucky K in Ohio

Advantages and disadvantages of suspension bridges?
It is good that they are flexible, however when very bad weather happens it can be bad. They are also bad for heavy loads. Two advantages are that they can be built high and they do not require a lot of material to be built.
What are the bad things about reinforced concrete?
It is quite expensive and isn't very god for the environment, it lets of emmisions into the atmosphere and is very ugly, yet it is veruy reliable and strong. Go subflooring instead.
What influence the choice of materials for marine engineering component?
It is important to that we understands the specific usage of a certain material, the conditions on where the materials is likely to fail and how to effect an efficient repair. Bad materials mean accidents, and accidents cost lives as well as a lot of money, or possible loss of ship.
What documents or information is provided by a project sponsor?
A project sponsor will typically provide some or all of the following:authority to use the resources of the organization to execute the projectthe business casethe scope, and guidance on scope managementthe budget, and guidance on burn rateguidance on quality, critical success factors, and other understandings of what will constitute "done"the "done by" datean introduction to the key stakeholdersfacilitate access to resources, from people to technologygovernance, including acting as chair of the steering committeea political back stop, when you have to say "no" to change requestsA good project sponsor will "fly air cover" for the project manager and project team; a bad one will make the team wish they had someone to fly air cover for them. Your earliest meetings with your project sponsor will give you the chance to exchange your expectations of each other; use them wisely.
What other energy sources could replace the use of petroleum?
There aren't many energy sources that can replace petroleum. Petroleum - gasoline and natural gas - is both energy-rich _and_ easily portable; very few energy sources meet both criteria. In most applications, you would need to combine two or more power sources to replace the petroleum. Electrical: In order to be portable, you'll need to store the electricity. Batteries are heavy and not particularly efficient. Charging the battery can take considerable time, and the batteries themselves can undergo a finite number of recharge cycles before they need to be replaced, and batteries can be expensive. The electric energy used to recharge the battery has to come from someplace, and that's generally a power plant that uses hydroelectric, nuclear, coal, oil, or natural gas. Wind: Wind power isn't constant, and varies too much over the course of a day. We can't use wind power for vehicles, although sailing ships using solely wind power crossed the oceans for hundreds of years. Nuclear: Nuclear power plants are massive. They're "portable" in ships, but not in land vehicles. Nuclear powered ships can sail for a couple of years before needing to be refuelled. Hydroelectric; Hydro-electric power is generated by using running water to spin turbines to generate electricity. At its simplest, this can be something as simple as a water wheel, but to generate substantial amounts of energy, we'll need a large volume of water falling quite a distance. That means a high dam, with lots of water behind it. That's not at all portable, of course, but it's generally pretty reliable and constant. The flooded valley behind the dam can have its own costs; however, the water storage, flood control and recreational resource aspects make hydroelectric dams an attractive option. Solar: Solar power works as long as the Sun is shining. You'll need batteries (see above) for night time or periods of bad weather. Alcohol-based fuels; We can convert plant matter into alcohol and use the alcohol as our portable fuel. However, alcohol contains less energy (fewer BTUs per gallon) than gasoline, and the plant materials aren't easily fermented to produce alcohol. In current alcohol production, it takes gasoline and natural gas to make the alcohol, so we often get less energy from the alcohol than we spent in fossil fuels to make it. Also, current alcohol production is almost totally dependent on corn, so we're using food to create fuel. The price of corn has recently risen high enough that some people are struggling to afford the food that we're turning into alcohol. And if we devote acreage to grow some other plant, we're decreasing the amount of edible crops we can grow. It's sometimes an uncomfortable tradeoff.
Is there a way to tell if the power window switch is bad or if it the motor for the switch?
remove switch from where it is mounted using a wire , bridge the connections.if switch is bad, it will work the motor while bridged

How do you check a bad centrifugal switch on dryer motor?
If the dryer has a button that says "Push to Start", and you push it and nothing happens, the centrifugal start switch is bad. If you can get to it, and it is an "assembled" switch (as opposed to molded or sonically welded), you can disassemble it and clean it with electrical contact cleaner (available at the large retailers). That will fix it for awhile - possible a long while. But it is not terribly expensive, and to order the factory specified replacement switch for it online is a permanent fix.
