1. The problem statement, all variables and given/known data I have to find the center of mass of any vehicle. 2. Relevant equations These are what I have to make. 3. The attempt at a solution Here is what I have thought. I have two solutions :- 1. To find the mass of all the major components and their centers and then equate with the total mass of the vehicle to find the center. My question. Do I need to find the reactions at the tyres ? I don't think so because after all their sum will be equal to the total weight. 2. I was thinking that if I have all the four reactions at the tyres computed directly then is there any way I can find the COM ?
