## Question:

Draw the free-body diagram of the smooth rod of mass $M$ which rests inside the glass. Explain the significance of each force on the diagram.

Given:

$M$ = $20$ $gm$

$a$ = $75$ $mm$

$b$ = $200$ $mm$

$\theta$ = $40$ $deg$

## Step-by-step

${ A }_{ x },{ A }_{ y },{ N }_{ B }$ force of glass on rod.

$M(g)$ $N$ force of gravity on rod.
