hello, i just started learning index notation in my engineering class, and im having some trouble. one of the problems on my hw was:(adsbygoogle = window.adsbygoogle || []).push({});

putting this in index notation:

[tex]\vec{f}=g \frac{m_1m_2}{\vec{r}^2} \ \frac{\vec{r}}{\sqrt{\vec{r}^2}}[/tex]

and then another problem that reads...

consider a plane with outer normal vector [tex] v_i [/tex] on which a force is acting [tex] f_i [/tex]. what are the normal components of force on the surface? wut is the max shear component? what direction is the max shear component pointing? write this in index notation.

i can figure out the components...just not how to write them in index notation. so any help here would be appreciated. thanks
