yes,yes,yes,,no problem...( farm boy,man,whatever )

a turbo will blow ur motor, get a cold air intake its pretty cheap and it will give u about 10-20 more horse

you can pin it to the frame and wind it around the axle by pulling it backwards, you can use the "propeller" method. basically a balsawood plane with wheels and no wings. Or you can use the rubber band as a slingshot any of these will propell the car up hill or otherwise\n\n Well...\nFrom the materials list alone, it's clear that this is a "professional grade"\nrubber band project. The #107 rubber band is a 5/8" x 7" size, which can\nstore quite a bit of energy. And you'll need it, since you're climbing a\n16 foot ramp with a load. I'm not sure exactly how you "pick up" a 50 gram\nload, but I'll assume that it's suspended over the track so that you don't\nrequire a mechanism to grab it, just drive under and it falls onto the tractor.\n\n\nThe problem then is that you need to balance your gear ratio against the\nweight you have to carry. At the start, you can afford a higher gear ratio\nbecause you don't have much to carry. As you move, you need to "gear down"\nto pull the heavier load. If you just gear it low to start with, you may not\nhave enough travel distance to make it to the end. If you gear too high,\nyou won't be able to pull the heavy load near the end.\n\n\nI'd look hard at a stepped-drum variable transmission. If your drive axle\nhas a series of stepped drive drums, with the smallest unwinding first, then\nyou have a high gear ratio for the first stage that goes far enough to pick\nup the first weight. It then steps up to *just enough* bigger that it can pull\nthe weight, and continues to the second step. Another step up just before\npicking up the next weight, and so on until you reach the end. You use up\nmore rubber band travel at the lower gears near the end, but you've saved\nthe travel during the early part of the pull.\n\n\nI'm thinking that your four feet of string will suffice for the drive system,\nso long as you can can stretch the rubber bands from a support at a distance.\nYou should measure the maximum stretch you can get from a rubber band, and\nfigure from that how much string to use, then use that to derive the drum\nsizes, then take *that* and work out the wheel diameter. If you get a choice\nof "string", I like 90lb test braided dacron fishing line. It's light, easy\nto work with, and much less lossy than cotton string. One option might be\na "boom-style" string puller, with the string attached to the end of a rod\nthat pivots at one end, and the rubber bands anchored to a sturdy structure\nthat pulls the rod. You can vary the attachment points of string and rubber\nbands to get the best balance of pulling force and stroke length, but you\nneed to make sure there won't be overhead obstructions on the track.\n\n\nEfficiency is important; do the best you can to make things smooth, be\nsure there's no binding in your bearings, and look hard at energy losses\nthroughout the system. This is an energy-management problem really, and\nyour task is to take a limited energy supply from the rubber band and spend\nit wisely to *just* achieve the goal. If you can, design your rubber band\nanchor so it can be adjusted, and do your prototype test runs with the\nband stretched to about 70% capacity. That gives you some margin for\nvariables, when the real test comes.\n\n\nHere's a pick of a simple design http://www.balloonhq.com/balloon_car/27.html, here's another pic http://www.plumcreekmarketing.com/07science/01images/fullsize/164304.jpg and another pic http://www.marshall.edu/lego/ati/ATI_LEGO2.htm

First let's consider the turning radius of the tractor alone. You need to specify the steering angle of the front wheels, and the wheel base (distance from front wheels to rear wheels). If you want to know the minimum turning radius you need to know the maximum steering angle. Consider just a single steered wheel and rear wheel for simplicity. During a turn the steered wheel follows a large circle with radius R1 and the rear wheel a smaller circle with radius R2. Both wheels are tangent to their respective circles since there is no sideslip. A diagram of the steering situation would start with an arc of the outer circle with angular extent equal to the steering angle Theta and radius R1. One end of the arc is designated the 0-degree point. The steered wheel is oriented tangent to the arc at Theta. A radius A is drawn at the 0-degree point. A line is drawn perpendicular to A from the steered wheel. The length of this line is the tractor wheelbase L. The inner radius R2 is the distance along A from the center to the wheelbase line. A right triangle with sides R1, R2 and L can be formed by drawing radius R1 to the steered wheel; with L and 2 angles known, R1 and R2 can be solved for.  \nSimilarly if you want the minimum turning radius of a tractor-trailer combo, you need to know the maximum angle of the tractor relative to the trailer. (If it is greater than 90 degrees, the minimum radius will be obtained at 90 degrees; the center of the trailer's rear axle will stay put.) This angle is now defined as Theta. Then apply similar thinking as per the above, but now R1 is the radius of the tractor's rear wheel circle and R2 the trailer's rear wheel circle, and L is the distance from the tractor's rear wheels to the trailer's rear wheels.  The turn radius is slightly larger than R1 due to the tractor wheelbase extending tangent to R1.

you need tight trucks to retain control at high speeds

ok first , you might want a treestand. and public land ( aint good!!) then a 30-06 cuz itll take em down, ( shoot behind the front leg)

The fuel should increase to take the load. My experience is on turbine generators, one was 9 mega. WATS.

Not a lot.  18-20,000 pounds.

i would assume it depends on what you are plowing

FOR AN 18 WHEELER YES AS WE PAY THOUSANDS EVERY YEAR  UNLESS YOU CAN FIND ME A HIDE AWAY WHEEL SYSTEM LIKE GREYHOND AND SOME DUMP TRKS HAVE

round up works well. state road crews use it commercially so that should give you some indication

Many jurisdictions allow a maximum weight loading per axle for commercial vehicles.  When a concrete (cement is the powder that glues concrete together) truck is fully loaded 9 to 10 yards, it will typically exceed the maximum allowable load.  The extra wheels are called a dolly.  These are hydraulically operated wheels that help spread the load onto another axle and therefore bring the truck into compliance with axle loading limits.  When the load is delivered and the truck is empty, the extra axle is raised to help reduce the turning radius of the truck.

M-16s?  No.  Not powerful enough.\n\nDillon 20 mm mini-guns installed on HUMVEES and Apache helicopters.  And land mines.  Let's not forget land mines.

They have taller, skinny wheels that are just high enough to keep the undercarriage from contacting the ground.  They use them just to get the truck into the 18 wheeler.  The wheels come in a different truck.

depends on the size of the shovel
