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
