% Of Weight That Is Pin Weight
Saw this on another forum...sounded interesting, and makes sense.
When adding weight to the storage areas of 5ers, the question always arises as to how much of that weight goes on the pin as pw. Here is what a mechanical engr on the other forum stated:
1. Measure the distance from the center of the two axles to the pin.
2. Weigh the 'stuff' you are storing.
3. Measure the length from the center of the two axles to the center of mass of the 'stuff' you are storing.
4. Compute the percentage of distance from the measurement in #3 as compared to the measurement in #1.
If #1 is 20' and #3 is 12', #3 is 60% of the distance from #3 to #1. Therefore, if the weight added is 500 lbs, 60% of it, or 300 lbs goes to pw. Don't know how accurate this is, but at least it's a ball park figure.
