OK, 9 lb weight for the bearing/platters was an initial estimation; if you take a look at my responses to Bill K, you will see that I have put the weight at 8.44 lbs.
So this makes the weights you calculated:
* upper LH point (A): 4.35 lbs (instead of 4.64 lb)
* lower RH point (C): 1.52 lbs (instead of 1.62 lb)
* upper RH point (B): 2.58 lbs (instead of 2.75 lb)
... which agrees very well with Bill's calculations. Which were:
* (A): 4.30 lbs
* (C): 1.53 lbs
* (B): 2.61 lbs
So thank you, Todd. :-))
Now, here is a slightly more complex scenario - which is the actual situation ... include the weights of the arms which are cantilevered out from the 2 RHS apexes of the triangle.
Here is your diagram - suitably modified:
I would be interested in what your opinion is of the resulting weight balance. As I see it, because the arms are cantilevered out from B & C, there is a negative action on the apex which is at the other end of that particular triangle side?
So:
* the 0.99 lb arm outboard from B reduces the weight at C, and
* the 1.65 lb arm outboard from C reduces the weight at A?
But how to calculate the resulting apex total weights, with these cantilevered weights? :-))
Is it simply according to the relative distances? So:
* at C, weight is reduced by the fraction 2.0/7.95 * 0.99 lb = 0.25 lb
* at A, weight is reduced by the fraction 1.6/16.9 * 1.65 lb = 0.16 lb.
But should this decrease in weight be added to the weight at the fulcrum apex ... so that the total weight increase along each triangle side, sums to the weight of each cantilevered arm?
Regards,
Andy
