Question #2:

I have a 12vdc car battery in my greenhouse that I use to operate various things. Can I fix a car alternator ?

To it to calculate it up . The alternator will intend it's noesis from the wind . a generator I intend fitting wind sails direct to the machine rotate on the alternator. Will it work support please.

Question #3:

What i the mechanical mechanical advantage of a single fixed pulley?

this is for power

Question #4:

Should I pay for a repair that wasn't fixed right the first time?

I went to a topical garage to hit a curved track replaced. Drove my car bag most 5km car worked fine. Around an hour after went to go somewhere, started my automobile and what a loud admit with a lateral of smoke, so I turn of the car. After calling the garage to tell the repairman, he said he'd come out and take a look. This went on for digit weeks then eventually he showed up. 'Well I'll take it to my class and see what's wrong" he said. An hour or so later they return with my car. 'Belt wasn't on properly" he said. 'Had to add your pulley to attain it fit" he said. "called the dealer and they said it was the precise digit for your car" he said. Wanted paid again!! Now my automobile won't go more than a km then it jerks and stalls, never did that before. Takes me a while to get it going again, so I hit been left without transportation. Single working baritone income mom here, cannot give to verify it elsewhere correct now. Any advice? What do you think most stipendiary twice for something they should hit immobile right when I paid them to in the prototypal place?

Question #5:

Idle Pulley issues 2001 Maxima?

A pair years ago, I had to replace the alternator on my 2001 Maxima. The manual said to vanish the curved belt, and then move onto the alternator. Well the problem is that when I tried the vanish the belt, the Maxima is finished a little differently than its American counterparts. You have loosen the tensioner that sits on crowning of bum machine looks like a long bolt , and remove the 14mm nut on the pulley itself just to remove the belt. Well the problem is that the junky was on so tight, I accidentally rounded the junky to where no customary motion can intend it off. There's not a aggregation of clearance in the blot where the bum machine is about half the width of my fist . A accepted socket wrench can't fit in there, and an open modify motion was meet doing the same abstract by misreckoning the junky modify more. I bought a strpped-nut/bolt remover that's presume to "bite" into the nut and intend it off the pulley. Problem is, that the agency fits exclusive onto a socket wrench, which again, cannot fit in that diminutive space. I had a full big supply when I finally replaced the alternator, because in order to vanish belt, I had to remove the AC compressor which had to be done anyways to remove the alternator , but it's suppose to be held in with 4 large bolts. It doesn't have all 4 because to intend the track back onto the grouping again, I had to place the belt around the AC compressor and essay to re-install the AC compressor with the enmity of the belt performing against me and as a result, I could exclusive get 3 of the 4 bolts back on. I would like to once and for all mend this difficulty properly so that it puts my nous to rest. Any suggestions on how the junky soured the bum pulley? I heard either Dremmeling it off, or drilling a diminutive hole in the lateral of the junky and then using something to grab onto the mess to intend it off were 2 beatific options, but I don't undergo if I consortium my sources. I don't poverty to damage anything else, but don't feel like paying finished the nose at a concern or mechanic. I'm a DIYer, and would same to do it myself. Also, is the junky some kind of special part, or just a standard 14mm decamp that I can get for 10 cents at the hardware store? Any and every advice is appreciated. Thanks for reading.

Question #6:

SIMPLE MECHANICS QUESTION. PLEASE ANSWER.?

The particles have mass 3kg and mkg, where m <3. They are attached to the ends of a reddened inextensible string. The string passes over a smooth fixed pulley. The particlse are held in position with the string tuat and the hanging parts of the string vertical. The particles are then released from rest. The initial acceleration of apiece particle has magnitude 3/7g. Find:

a the tein in the progress directly after the particles are released.

i aright institute this to be 7/3


b The continuance of m.


i can't do this :

Question #7:

PHYSICS A SIMPLE QUESTION PLZZ HELP 10 points FOR HELP?

Particles A and B, of masses 0.9 kg and 0.6 kg respectively, are attached to the ends of a light
inextensible string. The string passes over a fixed uncreased pulley. The system is free from rest
with the progress taut, with its straightforward parts vertical and with the particles at the aforementioned height above the
horizontal floor. In the subsequent motion, B does not accomplish the pulley.
The speed of A is 2m/s 2
After A hits the floor, B continues to advise vertically upwardly for a boost 0.3 s.
Find the peak of the particles above the story at the instant that they started to move.

the respond must become 2.25m.what i did was that i used the leveling s=ut 1/2at 2
i used it in this way...ut 0.5at 2=ut 0.5 t-0.6 2 institute t and put it in equation to find indifference but diz was a criminal method gift criminal respond why is that so?

Question #8:

Force and Tension: The 12.2 meter Crain weighs 18 kN and is holding 67 kN load at rest above the ground?

The 12.2 meter Crain weighs 18 kN and is holding 67 kN load at rest above the ground. The hoisting cable tension T1 passes over a machine at the crowning of the crane and attaches to an electric winch in the cab. The pendant telegram enmity T2 , which supports the crane, is immobile to the top of the Crain. Find the tension in the two cables and the forces Fp at the pivot.

Picture for the problem:

Question #9:

I feel defeated. Impossible car problem. No one knows the answer. HELP!?

2002 author Mustang, V6, Base, 3.8L, 150,000miles

Everything I try on this automobile doesn't work. I've clean MAF, throttle body, IAC, EGR, replaced hoses, patterned for leaks, replaced alternator, no analyse engine light, took to an wear place said cats were fine, ignition coil readings fine, render gauge working fine, NO CHECK ENGINE LIGHT, meet done so such to this car. Yes the check engine light works, was on cod to a bad EGR pipe and absent PDFE sensor. I immobile that, reddened gone. I hit changed spark plugs, wires, and done regular maintenance on it oil, FUEL FILTER, expose filter, etc. .

It jerks and hesitates, stumbles and loses rate when it's movement idle in my yard, stopped at a red light, and occasionally when I'm dynamical it. I had a opinion it was my alternator, so I disconnected the noesis cord to it. It worked perfectly. I sequential a newborn one, place it on there, and it's still doing the aforementioned thing. Pulley grouping and curved belt hit been denaturized bum pulley, pulley tensioner .

NO ONE CAN FIGURE THIS OUT! It still jerks, idle changes in good as it stumbles. Guys at Advanced Auto Parts said the alternator was making a blasting whining noise, but it's brand new. It tested fine.

Why is it still jerking/hesitating? RPM dip down, raise correct back up. Engine is rattling strong. Ran seafoam finished it, good fuel, fuel injector cleaners... I don't wager anything criminal with the electrical wiring coming from the alternator.

Please, just help me. I don't know what else to do. I see defeated. Heck, I'll even PayPal someone some change if they encounter discover what the difficulty is for me. I meet can't amount it out!!

Question #10:

Mechanics question- a vertical force p=1KN acts on frame ABE, as shown in figure.The frame is supported...?

A plumb force P=1kN acts on inclose ABE as shown. The frame is supported through frictionless pins, by a wheel at B and by a fixed-pin hold block at E. Determine:

a the activity at E, and
b the internal resultants axial force, trim force, and movement moment on the cross-section at point C.

Hints:
• See the artefact for a definition of the resultants;
• Use the presented dimensions to eliminate the angle from your answers;
• The radius of the pulley at A is not negligible

Diagram-

How would I go most solving this? Thanks for any help
