5 ounces.
The maximum weight limit for a pinewood derby car is 5 ounces. Plan on adding 2 to 3.5 oz of weight to your car, depending on your car design and the weight of your pine wood block.
Can you add weights to a Pinewood Derby car?
In most races, a Pinewood Derby car’s weight is limited to 5 ounces. If your car weighs less than that, add coins or other weights.
Where is the best place to add weight to a Pinewood Derby car?
Best Location to Weight Your Pinewood Derby Car
When deciding on where to weight your car, you should try to reach a final balance point of the car 1 inch or less in front of the rear axle. To achieve this, place 2/5 of the added weight behind the rear axle, and the remaining 3/5 in front of the rear axle.
Do heavier Pinewood Derby cars go faster?
Much has been written about the physics of pinewood derby cars, and this is one rare case in racing where heavy = fast. Aerodynamics have little effect in such a short race, but weight does and putting the weight at the back of the car will make your car faster on the flat of the track.
What kind of weights can I use on a Pinewood Derby car?
Tungsten is the best weight for your pine derby car because it allows you to pack more weight in a smaller area giving you more flexibility in your car design and more accurate weight placement for speed.
How much extra weight can you put in a car?
While load capacity varies between different types of cars, the general consensus is that your average car can hold about 850 lbs. This is the equivalent of five 170-pound passengers. If you regularly exceed 850 pounds, most cars will begin to show signs of worn tires, poor suspension, and worn brakes.
Does adding weight to a car make it slower?
Adding extra weight to your car will slow acceleration, but won’t reduce its top speed. In determining a car’s top speed, its engine battles two main forces: rolling resistance and aerodynamic drag. At very high speeds, air resistance makes up the vast majority of the overall drag on your car.
Should I bake my pinewood derby block?
Should I bake the pinewood derby block? The short answer is no, do not bake the block. The idea behind baking the block is to remove moisture which will make the block lighter. You can then add more weight to the back of the car.
Does a longer wheelbase make a pinewood derby car faster?
The longer the wheel base, the greater the turning distance (a short car turns much more quickly than a long car). A pinewood derby car should go as straight as possible, so a longer wheel base is an advantage.
Should a pinewood derby car be light or heavy?
8. Add Weight: Remember to make your Pinewood Derby car as heavy as the rules allow. In general, it’s best to place weight to the rear of your car because a heavier rear increases speed.
Should I glue pinewood derby axles?
7. Create Glue Holes: Glue the axles firmly in their holes to ensure that they stay perfectly placed, but make sure you don’t get glue on your wheels. 8. Add Weight: Remember to make your Pinewood Derby car as heavy as the rules allow.
What is the fastest pinewood derby shape?
But aerodynamics rule the day, and the best shape is a simple wedge. Just like a spoiler on the rear of a sports car, the wedge shape allows as much air to flow over the top of the car without hinderance while keeping the car pinned to the track.
Should you sand pinewood derby wheels?
Sand and Polish Your Wheels and Axles
Design the fastest car at the Pinewood Derby and prepare for a fun race against other Scouts!
What makes a fast pinewood derby car?
One of the most important ways to make a fast pinewood derby car is by adding weights. Because the cars are relatively light, they need to overcome friction and air resistance when navigating down the racetrack. Most modern tracks feature an initial slope followed by a long, flat section.
Is graphite allowed in pinewood derby?
Pinewood derby race rules do not allow racers to add additional graphite to their axles between heats. As a result, the graphite blows off the axle with each run down the track. As the graphite blows off, friction increases, and your car slows down.
What is the best weight for a derby car?
The more your pine car weighs, the faster it will go on a downhill ramp. Most rules specify a 5 oz. maximum weight. Most Pinewood Derby cars weigh between 1.5 oz and 3.5 oz (depending on design) without weights so a car may need 3.5 oz or more of additional weight.
What happens if you exceed weight limit on car?
Overloading any vehicle beyond its rated capacity can and will bend the frame and damage suspension components. This is particularly likely if you hit a bump while overloaded.
What happens if you go over car weight limit?
Overloading Voids Your Insurance
Overloading a vehicle is actually against the law. This means that if your vehicle is involved in an accident while it is carrying too much weight, your insurance coverage can be voided. We don’t have to tell you how much this can cost, especially if you car is totaled.
What happens if you go over weight capacity on car?
Auto manufacturers recommend a payload capacity for every vehicle; it’s the maximum combined weight of all passengers and cargo that can be carried safely. Exceeding the payload capacity stresses the tires, shocks, suspension and springs – four parts of the vehicle that keep it under control and on the road.
Do you go faster if you’re heavier?
In principle, a lighter mass will accelerate at a faster rate under the same pedalling force. Yet, at the same time, a heavier rider will have more gravitational force and more momentum preserving their speed.
Does a heavier or lighter car go faster?
The air resistance is basically only affected by the shape of the car, so it will be completely unchanged. The heavier car, however, will have greater ground friction from the contact between the wheels and road and because of that will have a slower max speed.
