$4\mathrm{.}4$ Results and analysis for plate clutch

Instructions

Radiuses of plates $1$:$2$ and $3$ are shown on the appendix page.

Mean radius is the average of the radius of each plate.

On the table, your given add the weight $($W$($in newtons$))$ column und torguc $($thoretical and

experimental$)$ after your calculations and tahulate the resuls.

Note that, The mass of the top$-$plate is $4\mathrm{.}89$ kg $,$ and the plate radius $=0\mathrm{.}125m(Rn{f}_n)$

$4\mathrm{.}4\mathrm{.}1$ Determine the mean radius for each plate

$4\mathrm{.}4\mathrm{.}3$ Assume that uniform wear:

Frictional torque $T=WR,($theoretical$)$

where $=$ Frictional coefficient

$R=$ average plate radius

$W=Mg($note $M=$ plate mass $+$ mass on top$)$

$\frac{T}{W}=R$

Thus $,=\frac{T}{WR}$

$65\mathrm{.}2276$

Determine $$ for each set of results. $($use W$/$T graph in $4\mathrm{.}4\mathrm{.}2)$

Determine the average value of $$
