<p>A control arm is a part of a car’s independent wheel suspension and supports against occurring
            cross forces. That means that it is a mass-produced component, so any material and cost
            reduction pays off. However, every weight reduction in cars is welcome in general
            because dynamic characteristics increase and less mass must be accelerated and slowed.
            The following figure shows the initial model and the optimized model:<br/><img class = "image" src = "../TsoExampleImages/conArmModel.png" width = "400"/><br/></p>
