    Can Vector Analysis Help Find Replacement Weights for Spin Balance?

    Thanks for pointing out the angles relative to the prescribed orientation. I confused myself with a reference I'm using... For better accuracy, r1 = r2 but do not equal rc. When you mentioned that both masses (m1 and m2) and their angles must be positioned equally from the mc weight to...

    Can Vector Analysis Help Find Replacement Weights for Spin Balance?

    Attached is my work thus far. theta1 and theta2 were drawn arbitrarily and are unknown. Their masses are unknown as well. If I assume the two replacement weights to have the same radius and on the same plane, how can I solve for their masses and angular locations? In my mind, I'd like to run a...

    Can Vector Analysis Help Find Replacement Weights for Spin Balance?

    I had a test article go through a spin balance service. The mass-radius and angular location of the correction weight, to achieve static and dynamic balance, interferes with another component on the test article (I'm unable to place the correction weight at the specified location). Using vector...
