Car accident costs?
I was involved ina car accidnet today. Not my fault. got rear ended . anyways. how much do you think it is going to cost to fix. 1995 Mitsubishi Eclipse GST. The tow truck guy said I should consider it totalled. Going out to insurance tomorrow. Got hit on the passenger side wheel on the back. It dented it and bent the wheel. Bad thing: Rims are 17″ Exel and paint job is custom. And the dent is alright. Pretty big. her suv’s air bag deployed and it leaked. Ford Escape. Im really surprised my Eclipse held up that well. I also spun in the wreck. She ran red light. Thanks
pretty sure its a bent rear axle and a big dent. and im gonna need a new rim
I paid $3500. If it matters
on kbb.com
Suggested Retail Value: $6,720 (doubt i’ll get that)
Trade in: Excellent- $3,325
good- $2,690
Fair- $2,350
i don’t know if thats how the insurance calculates prices.
It has 109,600 miles. leather, power drivers seat, single after market cd player, premium sound system, all power, sunroof, and spoiler, and premium wheels 17″, custom paint job
centripetal acceleration? question?
I’m stuck on this:
A wheel of radius 1.00 m is spinning with a constant angular frequency of 20.0 rev/min (convert to rad/s)
a.) what is the centripetal acceleration of a point on the wheel’s rim?
b.) what is the translational acceleration of a point on the wheel’s rim?
c.) what is the translational velocity of a point on the wheel’s rim?
Tell me why my perpetual motion idea won’t work?
Imagine a small device that resembles a ferris wheel. There are magnets spaced equally around the rim. There is another strong magnet at the bottom such that when the wheel turns each magnet around the rim passes close to it and is pulled by it causing the wheel to speed up.
Normally the wheel would slow down again as the rim magnet passes the stationary one and is attracted in the opposite direction. I get that. But imagine each rim magnet is enclosed in a small superconducting box which blocks magnetic fields. One side of the box has hinges so that it can open as it approaches the stationary magnet and thus the magnet within will be drawn toward the stationary magnet and speed the wheel up. As it passes the stationary magnet the box closes preventing the attraction that would normally slow the wheel again.
A bit of the wheel’s spin energy is used to open and close the box but if the wheel is large enough and the boxes small and light enough there should extra energy left over.
1992 ford explorer 4×4 help?
hello i have a 1992 ford explorer with auto hubs…the 4×4 was working fine. then today we got new tires on rims and put them on now when u hit the button the light comes on which is good but when u drive it i hear clicking in the front drive shaft(sounds like its near the hubs). so i went and tested to see if it was in 4×4. so i went in the mud and nope only the back wheels were spinning. so is there a cretin way the hubs are supposed to go in?? please someone help i need the 4×4 working by sunday! thanks dan
they are auto hubs! …….
