Getting the Best Performance From Your Polaris Ranger

!±8± Getting the Best Performance From Your Polaris Ranger

A stock Polaris Ranger 4X4 base cost is ,699 and it's not uncommon for an owner who is interested in high performance to multiply this cost three fold to build their machine to exactly what they want. This is not an uncommon theme for any off road vehicle from a dirt bike to a full blown off road truck. Performance costs money and high performance is the key to maximizing the fun you will have on your weekend outings.

There are several aspects of vehicle modification that are usually overlooked. Safety and suspension are two of the most important features of a properly built ride but they are commonly given minimal attention or they are completely overlooked all together. However, Safety and suspensions tie together nicely and they are easily done at the same time.

The Polaris Ranger is capable of having enhanced roll cages and bumpers added. The best time to do modifications like this is when you have the vehicle apart to build the suspension. The Polaris Ranger suspension is adequate for a stock vehicle but if you want more out your Polaris power plant you better budget for Polaris suspension upgrades. If you don't you'll lose precious horsepower going to the wheels because the suspension will not be able to react to the higher levels of torque. This causes serious loss of horsepower.

Another drawback to a stock suspension is the amount of travel that you will get. With a properly set up suspension you'll be able to traverse rockier terrain and you'll be able to get out of places that a stock Ranger would not be able to get out of. Really, a Polaris suspension is the way to go! An added benefit to a better suspension is usually an upgrade in tire sizes. A bolt on suspension will not allow you drastic changes in this department but it will allow you small upgrades to give a little added clearance. It's easy to understand the lure of a high performance off road machine. The benefit of the Ranger is that it can take two people on a great weekend journey through the woods whereas a four-wheel vehicle is designed for a single person and a completely built off road tuck and cost at least ,000 for a dependable vehicle. The Ranger gives a lot more for a lot less even with the added cost of upgrades.

It's important to make sure the job is properly planned and attention is paid to all elements that add up to a successful build like safety and suspension to ensure you are getting the most out of your power plant modifications and to ensure you are safe while out in the woods.

Building a go kart - Frame Cracks - Stress Failure Calculations

!±8± Building a go kart - Frame Cracks - Stress Failure Calculations

Be with us all going at one time or another: We have been a victim of failure stress. I also have a permanent loss of this kind, broke my shin, and broke a very important crossroads that require surgery ... But the most careful of us have a less painful failures:

Error

- A break rake in our hands
- Or take a board under our feet
- Or even a crack in our go-kart chassis.

The error can be traced back to an eventhigh stress or obvious miss-application of design intent:

For example:

- Jumping Go-Kart
- Or try to move the rocks with the rake
- Or jumping on a board that was too thin

Each of these instances are descriptions of the failure. The funny thing is that we are able to predict the failure of assimilation correct information (which are always available) and with the help of mathematical relationships.

Sounds fancy and complicated, but it really means:

Things have theirBreaking point, we can predict this breaking point with relative ease.

So, for them ...

First, a basic understanding of how to evaluate the failure is required.

The science of non-

Science is a system of thinking based on cause and effect.

Translation: A Cause (a Go-Kart flight obscene speeds) flies over a jump and lands on all wheels, but suddenly falls to the ground making ugly scraping sounds (the effect).

What otherVariables exist for this problem? Well, what exactly is the problem? A Broken Frame!

To the untrained eye, the failure would be perceived as the go-kart went over the jump, when in reality it is a failure, because the frame is not able to handle the jump to load.

What went wrong?

So, what is it that caused the frame?

This raises the question of what exactly was the failure?

The frame cracked pipes under the seat and basically ripped the tubesHalf and the Go-Kart bent down and scraped on the floor.

Thus, the pipes, cracked, and ripped and bent.

To further evaluate the problem, we see that the tube (single) or section has a thickness of material. This section of the material torn or ripped.

Key To Failure

The tearing of the material is the key to understanding the basis for the so-called stress. In fact, most of the materials have the possibility to extend, or be upset. Stress is evaluated as theAmount of force for the area that the force can act on the material divided.

Stress = Force / Area

So, for example, cable is a solid (0.0625 inch wire diameter) hang from the ceiling. I have a load on the cable 100 pounds. The tension in the cable is 100 pounds for the cross section of the cable, or 100 pounds / 100 pounds, or RIP 2 ^ / ^ 2 = 0003 to 32,594 psi divided

To predict whether the cable would snap or not, the stress would be approximately 36000 psi WellAs you can see, we're really up to 36000 psi and not hit the light near the weight would lead to SNAP!

What we did was just a prediction. 0.0625 A cable can only load so much, and that is 100 pounds!

Ok, what do I know? Because scientists have observed that steel (steel that is) breaks consistently at around 36,000 psi stress. In fact, special equipment has been designed to fail just because of material samples, day after day. What they do isValidation samples of the materials for foundries and steel mills made sure that people like you and I can predict with relative certainty, and the things that we do not pause in mid-kart.

To recap is so stress as force per unit area or defined

Stress = Force / Area

It 'important to understand that the area covers part of the overall strength of the part, because the forces pass through this area.

We understand this very well when you get a large rubber bandand compares with a small elastic. The main difference between the two is the cross section of the rubber band. The largest rubber band has more room to work with, and therefore exerts more force when stretched.

3 rubber bands when we were together equal the same power as the elastic large, that due to the larger rubber band has three times as much area as the tire is smaller.

So stress is the force that can take a part of the area. Once the powerexceeds the load capacity in areas of the company, it snaps, breaks, or stretches then snaps!

Next time ... Cross section and the relationship to fail
