The attempt at a solution So far I found TCE and TCD, but I am not sure how to find the components for TCA. TCEforce vector = 0i + 0.3685TCEj - 0.9296TCEk TCDforce vector = -0.5012TCDi + 0j + 0.8653TCDk TCAforce vector = ? I'm not sure how to get the force vector components for TCA from the figure. Can anyone help?
