Pinewood derby axles are one inch long, 0.087 inch diameter zinc plated steel nails.
A "connected axle" in Pinewood Derby is a continuous axle rod that goes from one side of the car to the other. They are usually found in "PineCar" brand kits and require small plastic caps at each end of the rod in order to hold the wheels in place. Check your rules if you are planning to use "connected axles". Most well written Pinewood Derby rules usually will NOT allow this type of axle to be used. Standard Pinewood Derby axles are small nails that are used to hold each tire in place (four of them in the standard kit). These are usually the preferred axle of choice. If your rules do not state a specific kit brand or mention the use of specific axle parts, you may be able to use the "connected axle" on your car; however, I do NOT usually find these axles to be an advantage over the nail type axles. Mostly because the small plastic caps are of poor quality and often fall off during racing which allows the wheels to fly off the car. I am surprised that none of the third party marketers in Pinewood Derby have come up with a solution to the solid axle (aka connected axle) problem.
what kind of stupid question is this? if the dia of the axle is larger then that of the wheels, the axle becomes the wheel and the "wheels" become the axle
the mechanical advantage is noting
The recommended size for a through axle to use with a 10mm diameter is 12mm.
The standard bike axle diameter used for most bicycles is 9mm or 10mm.
The standard bicycle axle diameter used in most modern bicycles is 9mm or 10mm.
No, quite the opposite.
The best method for determining the size of a bike axle is to measure the diameter of the axle. You can accurately measure it using a caliper or a ruler. Simply measure the diameter of the axle at its widest point to determine its size.
The ideal (not idea) mechanical advantage is 30/4 = 7.5
because the wheel turns through a much greater distance than the axle.but the smaller turn of the axle is more powerful.witten by-brenda v.=========================Answer #2:-- The fact that the wheel turns through a greater distance that the axle doesis a result, not a cause, of the wheel being bigger than the axle.-- The axle is not more powerful than the wheel. Ignoring losses, they must bothhave the same power. The axle's force is greater than the wheel's force, but to payfor it, the axle must turn through greater distance. Same as all the lever stuff.-- The diameter of the wheel needs to be greater than the diameter of the axleonly if you'd prefer not to have the axle scrape on the ground.
It is a Chrysler built axle with a ring gear diameter of 9.25 inches.
an axle to which a wheel is fastened so that torque applied to the wheel winds a rope or chain onto the axle, yielding a mechanical advantage equal to the ratio of the diameter of the wheel to that of the axle.
