i have a 98 pontaic sunfire this thing i have fixed it up there SHOULD be nothing wrong with this car. the only thing i can think that is wrong is the transmission and i hope to god its not the transmission and when it hesitates it makes a real loud sound i have a system in this car and i can hear it over the subs it sounds like its struggling but i have replace the exaust system the starting and charging system the whole engine has been rebuilt fuel system is new suspention (except for the rear struts) is new Brake system is new the cooling and ac system is newand i just dont know of anything else it could be plz help im desperate (if i think of anything else i will post it to).
yeah there is no noise but when i take off it just makes a loud noise like creaking door only louder and no it does not try to move and it ussually doesent do it when the cars been drivin for more than a hour

and the uniform rigid aluminum strut has a mass m2 = 41 kg. The strut is hinged so that it can pivot freely about it s bottom end. The angle between the left wire and the ground is Θ = 26o and the angle between the strut and the ground is φ = 44o
a) What is the tension in the vertical wire that holds the steel block?
b)What is the tension in the left angled wire?
c)What is the horizontal (x) component of the compressive force in the strut?
d) What is the vertical (y) component of the compressive force in the strut?

The system shown to the right is in equilibrium. The steel block has a mass m1 = 205 kg and the uniform rigid strut has a mass m2 = 41 kg. The strut is hinged so that it can pivot freely about it s bottom end. The angle between the left wire and the ground is Θ = 26o and the angle between the strut and the ground is φ = 47o

a) What is the tension in the vertical wire that holds the steel block?
2009 newtons(Got the answer)

b) What is the tension in the left angled wire?

7184.43 NO (Arggghhhhh..really really really irritating me now)

c) What is the horizontal (x) component of the compressive force in the strut?

d) What is the vertical (y) component of the compressive force in the strut?
well- I can get c and D once I figure out B but for some reason I cannot get it...
This is the formula I used(I got this from the book- I think its wrong)
T=(M+m/2) Sin (47)/sin(21)

use this link for the picture..thanks
Anyways I figured out the answer for the problem myself a couple of days ago..its actually quite easy- I was using the wrong angle you see. Nevertheless- you were the only person that answered so i lle give you best answer

I posted in here a little while ago about my 2000 Grand Am bottoming out (LOUD knocking sound heard/felt) over bumps. Most said it was probably struts- and GM confirmed this after a road test..so they replaced both rear struts. But It s STILL bottoming out! What s even more strange is that when I take the car out of reverse or park- put it in drive and go- it feels like the wheels are rubbing against something..and there s a bit of a "thump" then there s a loud squeaky noise from the brakes for a few seconds.
My question is..what else is causing the bottoming out??? I just spent $600 with labour to replace the rear struts It s scary to the point where I don t want to drive the car anymore because the sound is so loud/distracting that my nerves are literally shot. Anyone know?

With more to offer than David Beckham-a deep brown voice and wonderfully large feet? Forget the money - there s more to life than that. How many more feel the same way? No-way i m going to let mine do that- the village would be swamped with lustful women!
edit: sorry lost the link to the Beckham photos! Can someone help?
Jomamo - you re confusing me!
Hawk - that s more than DB has to offer!
Stormy - is that why you picked that name? Actually i d be on the beat with him if that s what they re doing! No - not as a partygoer!
Mike - you ll have to explain that one pleae.
Haz - that s brilliant - especially the knickers thing - not too many women would admit to Bridget Jones pants!
Hooded Claw - thanks for the link! As for the Dame - well coupled with the avatar - what can one say?
Claw - getting back to the link - a pair of tennis socks? - definately not football socks!
Tank - this could be your moment in time! Go for it! Da da da- da da da da with a bump and a little gyration here and there she might make some money out of you!
Wow Elsie 19 you ve really got the party gear on tonight!

To-morrow- and to-morrow- and to-morrow-
Creeps in this petty pace from day to day-
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out- out- brief candle!
Life s but a walking shadow- a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an idiot- full of sound and fury
Signifying nothing.
