How Is Riding A Quad Bike On Sand Related To Physics

As mentioned. condition wise there are no limits as long as the speed is low enough.As you cycle you muscles will build up lactic acid. The harder you workout, the more you will generate. This acid makes your legs heavy and cause Myalgia (muscle pain). But, your body is capable of breaking this down. The more you train, the more your body is capable of coping with this. As long as you stay below this level that your body can handle you can keep going as long as you eat and drink enough.The main problem with an untrained body is getting used to the seating position. Saddle soreness is also something to get used to, and that will come up after a day, and takes sometime to get used to. But you fight through pain.

OK…. Imagine you are holding the end of a broom vertically in your hand with the head up in the air. It is perfectly balanced. Now move your hand and the end of the broom to the left… Which way does the broom fall?… to the right.the broom falls to the right because the broom has inertia and although the bit in your hand moves with your hand, the top bit lags behind because it has mass.How do you retain the broom’s balance?… You move your hand rapidly rightIf you want to turn right on your bike, you ACTUALLY turn the bars slightly left, and your bike then falls to the right, just like the broom head did.NOW, you turn the bars to the right to ‘meet’ the fall and use centrifugal force (which is using your forward speed to lift the bike back up and tip it towards the outside of the circle you are riding around) to offset the fall towards the inside of the circle.you are now at balance with gravity pulling you in, and centrifugal force pulling you out.To come out of the corner, you now turn slightly MORE right, tightening the curve, increasing that centrifugal force which overpowers the effect of gravity and your machine moves towards standing vertical. As it reaches the vertical, you centre the bars, removing any force acting on the bike, and continue in a straight line.

One thing I have learned recently is that it matters how deep the gravel is. I have been putting gravel on my sloped driveway recently. Where the gravel is thin (1 or 2 layers deep), the traction is significantly better than where the gravel is thick (5 to 6 layers deep). I'm using 3/4" crushed gravel so the thin gravel is 1/2" - 1" and the thick gravel is 2-3".It also matters whether the gravel is crushed or round, and how much it has been pushed into the road bed. The round gravel that is freshly applied (not pushed into the road bed) is almost like marbles under the tires.I think that is why a thick layer isn't as effective. It doesn't embed into the road bed and the top gravel just keeps moving around on the gravel below it. If the gravel had more fine sand, it would pack together better, but then I have more risk of it washing down the slope. That already happened to me once.Obviously, this isn't a single number answer. At best, I think embedded gravel could be almost as good as asphalt. According to this source, that could be as good as 0.9. Friction and Friction CoefficientsWith fresh round gravel that rolls beneath the tires, it would be much lower. Maybe as low as 0.1 or 0.2

Friction is Everything.First things first, the phone which you are using to read this answer (assuming you are using app) is held properly in your hands just because of friction.Majority of the cases, friction is useless because of the energy losses involved when 2 components interact with each other.But there are a lot many things which would be impossible if friction did not exist.-You cannot write on a piece of paper-You cannot hold the glass of water in your hands-You would slip on the floor trying to walk-You cannot stop your vehicle after applying the brakes-You would start slipping from your chair-You cannot open up the bottle cap to drink water-You would go crashing in to the driver's seat while standing in a bus just like Harry in HP-Part-3-You cannot machine components of extreme accuracy-Hair Styling would be a mere dream-Lastly, your pants won't stay on their assigned place (embarrassing moment especially in front of your crush) Thank God Friction Exists..!! _/\_
