Which if you add it together gives 74cm. In your case though that would be impossible because the combine lengths of the other two sides adds up to 72.2cm so you could never exceed that.Also green triangle is meaningless because what you are opening is B > C. But there is another triangle and that is B > C > D, i.e. there is going to be a slight difference between the the B > C distance and the D > C distance and that relationship is not going to be 100% linear, but for the purpose of the calculation I'm going to ignore that small difference.Anyway, for the following:<ul> <li data-xf-list-type="ul">$side1 = 13.0; # min actuator distance joint to joint.</li> <li data-xf-list-type="ul">$side2 = 38.7; # polar axis to joint 1.</li> <li data-xf-list-type="ul">$side3 = 34.0; # polar axis to joint 2.</li> </ul>I get this:<ul> <li data-xf-list-type="ul">1cm = 1.71º</li> <li data-xf-list-type="ul">2cm = 1.7º</li> <li data-xf-list-type="ul">3cm = 1.69º</li> <li data-xf-list-type="ul">4cm = 1.69º</li> <li data-xf-list-type="ul">5cm = 1.68º</li> <li data-xf-list-type="ul">6cm = 1.69º</li> <li data-xf-list-type="ul">7cm = 1.69º</li> <li data-xf-list-type="ul">8cm = 1.68º</li> <li data-xf-list-type="ul">9cm = 1.69º</li> <li data-xf-list-type="ul">10cm = 1.7º</li> <li data-xf-list-type="ul">11cm = 1.7º</li> <li data-xf-list-type="ul">12cm = 1.71º</li> <li data-xf-list-type="ul">13cm = 1.71º</li> <li data-xf-list-type="ul">14cm = 1.72º</li> <li data-xf-list-type="ul">15cm = 1.73º</li> <li data-xf-list-type="ul">16cm = 1.73º</li> <li data-xf-list-type="ul">17cm = 1.75º</li> <li data-xf-list-type="ul">18cm = 1.76º</li> <li data-xf-list-type="ul">19cm = 1.77º</li> <li data-xf-list-type="ul">20cm = 1.78º</li> <li data-xf-list-type="ul">21cm = 1.79º</li> <li data-xf-list-type="ul">22cm = 1.81º</li> <li data-xf-list-type="ul">23cm = 1.82º</li> <li data-xf-list-type="ul">24cm = 1.84º</li> <li data-xf-list-type="ul">25cm = 1.85º</li> <li data-xf-list-type="ul">26cm = 1.88º</li> <li data-xf-list-type="ul">27cm = 1.89º</li> <li data-xf-list-type="ul">28cm = 1.91º</li> <li data-xf-list-type="ul">29cm = 1.93º</li> <li data-xf-list-type="ul">30cm = 1.95º</li> <li data-xf-list-type="ul">31cm = 1.98º</li> <li data-xf-list-type="ul">32cm = 2.01º</li> <li data-xf-list-type="ul">33cm = 2.03º</li> <li data-xf-list-type="ul">34cm = 2.06º</li> <li data-xf-list-type="ul">35cm = 2.09º</li> <li data-xf-list-type="ul">36cm = 2.13º</li> <li data-xf-list-type="ul">37cm = 2.16º</li> <li data-xf-list-type="ul">38cm = 2.2º</li> <li data-xf-list-type="ul">39cm = 2.25º</li> <li data-xf-list-type="ul">40cm = 2.28º</li> <li data-xf-list-type="ul">41cm = 2.34º</li> <li data-xf-list-type="ul">42cm = 2.39º</li> <li data-xf-list-type="ul">43cm = 2.45º</li> <li data-xf-list-type="ul">44cm = 2.51º</li> <li data-xf-list-type="ul">45cm = 2.59º</li> <li data-xf-list-type="ul">46cm = 2.66º</li> <li data-xf-list-type="ul">47cm = 2.76º</li> <li data-xf-list-type="ul">48cm = 2.85º</li> <li data-xf-list-type="ul">49cm = 2.96º</li> <li data-xf-list-type="ul">50cm = 3.1º</li> <li data-xf-list-type="ul">51cm = 3.24º</li> <li data-xf-list-type="ul">52cm = 3.43º</li> <li data-xf-list-type="ul">53cm = 3.65º</li> <li data-xf-list-type="ul">54cm = 3.91º</li> <li data-xf-list-type="ul">55cm = 4.26º</li> <li data-xf-list-type="ul">56cm = 4.72º</li> <li data-xf-list-type="ul">57cm = 5.4º</li> <li data-xf-list-type="ul">58cm = 6.52º</li> <li data-xf-list-type="ul">59cm = 8.93º</li> <li data-xf-list-type="ul">Total arc = 144.81º</li> </ul>It stops at 59cm because after that the variable length would be greater than the to fixed lengths added together and that is impossible for a triangle.</blockquote>
