Q:I‘m kind of confused as to what to do on this problem. I know that ωo (k/m)^1/2 which is the natural frequency, but I‘m not sure what to do with it. Could someone give me a hand?A car’s front suspension has a natural frequency of 0.45 Hz. The car’s front shock absorbers are worn out, so they no longer adequately perform their function of damping out oscillations of the front of the car (i.e., assume thedamping constant b 0). (a) At what frequency do you expect that the frontsuspension will experience resonant vibration (i.e., at what frequency will the amplitude of the front of the car oscillate with maximum amplitude)? (b) Now, assume that the car is driving on a bumpy road with bumps spaced roughly 40m apart. At a certain speed, the driver notices that the car begins to shake violently. What is the car’s speed?

What Hillary needs to do is heavily tax those companies that are moving to India and China and leaving our workers without jobs. Do you blame them? Why do you think they are outsourcing? It's not just about cheap labor. It's also, getting sued, over regulation in the U.S., and raw materials. And taxing them more is not going to create more jobs. That theory does not work, it will in fact create less. As far as taxing the oil companies, sure. But it always ends up trickling down to the consumer in the end. So what progress does that make? Hillary doesn't ever make sense, nothing new.

Q:I recently purchased a 2004 Mazda 6. It has 70,000 km on it (43750 miles). I notice that the ride is very bumpy. Basically I feel and hear every single bump or cracks on the road or the highway. Is this normal? If not what is it to blame?I am maintaining the tire pressure at the suggested 32 psi for all 4 tires. Should I be trying to vary this for improvement? The tires as you know are low profile (profile ratio: 50). I know these kind of tires are known to have a little bumpy ride. Or could it be the struts?Comments from any Mazda 6 owners would also be greatly helpful. Any mechanics out there would also be able to provide great answer to my question. Thank you all in advance.

No it will not hurt anything, but all you need to do is call your local dealer with your VIN # and the can tell you if it has a limited slip differential or not.

Q:I am 16 years old, going to be 17, and I live in New York.and I have always had a passion for cars. I have also had a passion for math, I have always been good at it, and it kind of runs in the family. So what are possible careers to major in college which combine my interests in Mathematics and Cars???Also, what Colleges would you recommend that offer this career ?

first thing would be check fuses to see if one is blown you got a owners manual it wil l tel l you which one it is but easy to pull one and look to see if they bad or not either way and you sure they not froze

Q:It got worse because i had to use smaller tires, out of necessity. So there was a lot of pumping up and a lot of air release at the end of the day. Everything worked ok till this morning (3months from the tires being put on) and now nothing is pumping up. I did not run over anything or scrape anything that i can recallalthough someone says there is a switch under the car related to the air compression? The lincon dealership scared the crap out of me and said diagnostic was $185, but that compressors are $400 and they easily do work on lots of peoples lincolns that run into the thousands on suspension systems.and i went outside and cried on the hood of my car afterwardsEven before i spend money; isnt there something i can do? If a compressor valve is stuck, for example - is there a way to unstick it? Maybe myself???? I can‘t get to work.been fired twice this month by picky temp agenciesnot a lot of money left!!! HELLLPPP!

I am afraid that is about right what they said. You could look around junk yards but do not expect much from there.

Q:I‘m 6‘4 and 250 lbs. I don‘t plan on doing anything fancy besides riding around town.I might go off sidewalks it would be mainly for getting to school and back instead of wasting gas. I would also like to have the option of going long distances. Thanks, Not sure what other info you need

metropol A great choice! You are at the extreme ends of bikes based upon weight. I would suggest a good Cross / hybrid bike or a mountain bike without a suspension systems. The suspension system, o the road, sucks the energy out of your pedaling. Make sure you go to a proper bike shop to be fitted, and discuss your choices. A cross or hybrid bike would be a better choice . but, make sure you switch out your off road knobby tires for smooth road type tires. It makes a big difference in road speed and comfort! A piece of advice. learn how to pedal properly by spinning the pedals. You should spin at a rate of 70 rpm minimum with moderate pedal pressure. Do not ''mash' the pedals a a slow speed in to hard of a gear. It makes riding faster and further, in more comfort possible. Soccerref

Q:I BOUGHT THE 2 AIR BAG SUSPENSION FOR MY 2000 BMW X5, HOW CAN I CHANGE IT?

Why? I certainly don't advise it, even if it were possible. If you want a machine to make all the decisions for you - ride in a cage.

Q:The main cables of a suspension bridge uniformly distribute the weight of the bridge when in the form of a parabola. The main cables of a particular bridge are attached to towers that are 600 ft apart. The cables are attached to towers at a height of 110 ft above the road. The cables are 10 ft above ground at their lowest points. If vertical support cables are at 50 ft intervals along the level roadway, what are the lengths of these vertical cables?a. if you knew the equation of tha parabola that the cable formed, what would you do with the information vertical support cables are at 50 ft intervals to find the length of these support cables?b. what are the coordinates for the vertex? What are the coordinates for the tops of the main towers?c. write the equation of the parabola going through these points in standard form.e. what are the x-coordinates of the vertical support cables?f. how long is each vertical support cable?please help!

? equation of each parabola ya*x^2+b, where b10 ft; also know that y(50/2) a*(50/2)^2 +10 110 ft, hence a0.16; thus y(x) 0.16*x^2+10; ? elementary length dL√((dx)^2 +(dy)^2) dx*√(1 +(y’)^2) dx*√(1 +(2*0.16*x)^2) dx*√(1 +(0.32*x)^2); hence ? Lx*√(1 + 0.1024*x^2) + 3.125*ln(0.32*x+√(1 +(0.32*x)^2)); for limits x0 until 25; L210.233 ft; ? I hope u cope with rest ur self; click me if stuck though!

Q:Im wondering if we could produce electricity from the suspension of a car.Please help me.And if we can how do we do it?

Sure you could. With the right mechanism, you can convert the mechanical motion of a suspension into a circular motion to drive a generator. But it is not worth it. The extra weight of the conversion mechanism and the generator (or alternator) would reduce the efficiency of your car. Then, if you want to store the energy, the weight situation would be even worse because you would have to add an extra battery because your regular car battery is normally completely charged and does not the capacity to store any more energy. You can also calculate the maximum amount of energy you can realize. Take the mass of your car (minus the mass of the tires and other parts that will not move relative to the suspension), figure out the maximum vertical travel, and the number of up and down cycles per unit of time. Then, using the acceleration due to gravity, calculate the total amount of energy available. Then, assuming a generator efficiency, you can calculate how many Kilowatt hours of electricity you can get. I imagine it will not compensate for the loss of mileage due to the additional weight.

Q:1994 sse

Pull the relay, should be located under the hood, but be prepaired to reinstall it, some cars need to be hooked up to the air supply or the air will slowly purge out of the system. Maybe take it to a garage and have the problem diagnosed as why the system is staying on, maybe bad wiring or maybe a leak in an air line. Fixing the problem is better then band-aid repair jobs. I did the same thing to my truck when the ABS started acting up on it, I know the problem, but its not worth fixing, pulled the relay, and the ABS system is deactivated. Same will work on air suspention.

Q:I got my license on a six month suspension 1 year ago, but it hasn‘t been officially revoked yet. Did someone just forget to process this and suspend it, or is this typically how long it takes to process a license suspension?

NO, that is not typical, 4 to 6 weeks is typical.}{
