Hello all, just a little centre of gravity question:
A 1.7m long barbell has a 20kg weight attached on its left end and a 35kg weight on its right end.
a) If you ignore the weight of the bar itself, how far would from the left of the barbell is the centre of gravity
- I had no trouble with this part and found the centre of gravity to be 1.07m from the left end
b) Where is the centre of gravity if the 8.0kg mass of the barbell itself is taken into account?
- I was stumped at this part: How could the mass of the barbell possibly affect the centre of gravity!? please help!
