1. The problem statement, all variables and given/known data i did a lab where we used a force table and pulleys/string to find equilbrants of vectors/forces. a question i'm having a hard time explaining is... why does the force table have to be level? what would the effect of having a tilted table have on the results? also...if the mass of each force/vector is the same for each, can the mass be neglected? 2. Relevant equations none. f=ma ? 3. The attempt at a solution for the first question... i know the results would be affected. i don't know if it has something to do with the normal force being perpendicular. or the mass and angle would have to be adjusted to accommodate for the unequal force on the tilted side. 2. i don't think it can be neglected because mass is part of the magnitude part of a vector quantity. any help or input?
