Hal itu dapat di buktikan dari gambar berikut ini. Yakni gaya berat dari W<sub>1 </sub>dan W<sub>0 </sub>disamakan oleh gaya dari fs dan gaya T ( tegang tali ). Gaya W<sub>1 </sub>dan W<sub>0</sub> yang arahnya ke bawah searah jarum jam ( CW ) disamakan oleh gaya fs dan gaya T yang arahnya keatas berlawanan jarum jam ( CCW ).<o:p></o:p></span></div><div class="MsoNormal" style="line-height: normal; margin-bottom: 0.0001pt; text-align: left;"><div class="separator" style="clear: both;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiqxpcLrPhkBA6zG1fU6tnWI7mxvQGCxOKcoAeetATfTq6j95pkoq5qywMzVGiAOJ3r3VDiud9zre1GmHx_6TLNXYcSHd3MNBfWjLiBFx7Kwimr0pk5RXbdfH_rPQhm-nk-2rKkd6RtLw/s1600/a.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiqxpcLrPhkBA6zG1fU6tnWI7mxvQGCxOKcoAeetATfTq6j95pkoq5qywMzVGiAOJ3r3VDiud9zre1GmHx_6TLNXYcSHd3MNBfWjLiBFx7Kwimr0pk5RXbdfH_rPQhm-nk-2rKkd6RtLw/s1600/a.jpg" /></a><span style="color: blue; font-family: "Times New Roman","serif"; font-size: 12pt;"><o:p></o:p></span><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjf8vv6OrYjrM0MI_9kQadIpM1K1brFpR728660GleJ5TE4Mza3VIWnDBNfSbybY341f4Csv9hqRsKbNfd5blPurUcDxu8C_6yVxzt-O6gyGpeAyiuMLjHSE0VOlko3wgpI2CTMW0ruNQ/s1600/tl.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjf8vv6OrYjrM0MI_9kQadIpM1K1brFpR728660GleJ5TE4Mza3VIWnDBNfSbybY341f4Csv9hqRsKbNfd5blPurUcDxu8C_6yVxzt-O6gyGpeAyiuMLjHSE0VOlko3wgpI2CTMW0ruNQ/s1600/tl.jpg" /></a></div></div><div class="MsoNormal" style="line-height: normal; margin-bottom: 0.0001pt;">

Momen Gaya dapat ditemukan dengan mencari Gaya (F) dan jarak titik A (poros diam) terhadap F (R) sebelumnya pada gambar. Gaya (F) dapat ditemukan bila diketahui panjang tali dalam cm lalu diubah ke Newton untuk menemukan gaya tegang tali (T) dengan skala 1cm = 0.1 Newton. Selanjutnya, Momen Gaya (Torsi (τ)) dapat dicari dalam satuan Ncm dengan rumus τ = F x R. <o:p></o:p></span></div><div class="MsoNormal" style="line-height: normal; margin-bottom: 0.0001pt;"><br />
</div><div class="MsoNormal" style="line-height: normal; margin-bottom: 0.0001pt;"><span style="font-family: "Times New Roman","serif"; font-size: 12pt;">Pada benda diam (setimbang), gaya yang bekerja mempunyai resultan = 0. Artinya setiap gaya akan saling meniadakan. Karena gaya-gaya tsb sama besar maka τ akan bernilai 0 sebab tidak ada gaya putar pada benda.<o:p></o:p></span></div><div class="MsoNormal" style="line-height: normal; margin-bottom: 0.0001pt;"><br />
