Comprehensive Study Guide for Centre of Mass of an Asymmetric Uniform Bar

In the previous calculation, the position vector of the centre of mass was determined as: rcm=L6i^+2L3j^\vec{r}_{cm} = \frac{L}{6}\hat{i} + \frac{2L}{3}\hat{j}. However, it seems there was a misunderstanding or error leading to the conclusion of 138Li^+58Lj^\frac{13}{8} L \hat{i} + \frac{5}{8} L \hat{j}.
To clarify the correct approach to finding the position vector:

  • The x-coordinate was calculated as xcm=L6x_{cm} = \frac{L}{6}, which comes from the average weighted position of the horizontal segment.
  • The y-coordinate was calculated as ycm=2L3y_{cm} = \frac{2L}{3}, based on the vertical segment's average position.
    If you have a different approach or if additional details substantiate your result, please share them for further discussion.
