papa, you should include the rider because the rider is an integral part of the system under study from a dynamic riding point of reference.... and as safe stated, the rider does shift around his or her body weight. i know for me, when going downhill, i'm sitting back while going up, i'm more...

that's right... but keep in mind the sun's mass is "spread out" and it rotates just fine, just as jupiter and the earth. what you will need to start addressing is moment of rotational inertia. btw, the discussion of weight distribution & it's effect on tire loading (and yes, traction, steering...

here's 3 of em... jj, smokr, and mando... and anudder shot of jj... and anudder shot of mando... here's saler, not pictured above... i even took em' backpakin' last year...

yep, go back to the posts stamped at: Mon, Sept 15, 2008 at 6:45PM and Fri, Sept 19, 2008 at 4:18PM safe, your model assumes the shape is homogenous to the extent that the (differential) density is consistant throughout the body.

they will be at the expo this coming weekend in santa monica.... in case anyone in so. cal is nearby and wants to see them person to person.

have you thought about reversing the motor by putting a fixed motor sprocket on the left side of the wheel and make the right side a freewheel? that would give you the option of pedaling with the motor or using the pedals as "foot holds" while the motor works. wondering what led you to this...

thanks :D i'll look into it.

bingo! (challenge to safe: let's see if safe can draw a PROPER 2-d vector diagram of this.)

consider that in a turn, the wheel axis are not parallel. your diagram is 2-d and does not reflect reality

nice try safe. but your attempt to manipulate yourself into a teacher position is failing when you can't even get the vector diagram correct. you see safe, when you make condenscending remarks like this: "(are you just being a "pain in the ass" or are you really confused.... come on.... be...

well, if that's truly the case, then properly explain traction and draw a proper vector diagram for a bike going through a turn. (hint, draw the forces exerted upon the bike at the contact points by the earth) please spare us the agony of having to sift through it all.

oh really? a 25,000 pound truck is headed for a solid wall at 70mph and hits the brakes. it begins to skid. do ya have 25,000 pounds of force as traction? what if it's in sand?, black ice? pavement? furthermore, how about if the speeds is difverent,,, say, 10mph verses 70mph in the above...

i've got 4 dogs to take out soon with my bike. worked on my bike maintenance yesterday (bleeding brakes) and so the bike's ready to go.... all i need is a rack. i just got a 2" hitch installed on my pickup (tacoma) and so i am looking for a rack that can fold down nicely which will let me drop...

we have similar issues with RC airplanes. the air enters thru the front of the engine cowling and we make the exit hole roughly 2x larger than the intakes. the point is to make sure air flows across the motor. you may or may not need to include baffles to direct the airflow where you want...
