Does your team not have a mechanical mentor?

If not, post a drawing of the arm in question, with dimensions, and someone here may be willing to help you understand how to do the calculation.

If you want just a very rough ballpark calculation, you could do the following:

- estimate the weight of the arm

- estimate where the center of mass of the arm will be in the lowered position

- estimate where the center of mass of the arm will be in the raised position

- take the vertical difference between the two center-of-mass positions and multiply it by the weight
