Hello, I am new here but am completley stuck on a lab that I need done for tommorow. I am doing a torque lab, with a meter stick being used as a scale and I know the mass of it. You can basically think of the meter stick as a seesaw with only one person on one end. I have attached weights to one end, and found the new centre of gravity. My biggest problem is, It says: Use your knowledge of torque to find mass of unknown. I am then supposed to find out the real weight by using a mechanical scale. I just can't figure out how to find the mass of unknown without using the scale. Can anybody help me out with that. Thanks alot!
