The hood is a simple shell structure that is subjected to two
<span class = "ph">load cases</span>.
Although one of the <span class = "ph">load cases</span> 
is unsymmetrical, the final design should be symmetric. 
<p><br/><img class = "image" src = "../TsoExampleImages/hoodsens_surfplanesym_model.png" width = "400"/><br/></p>
<p>The hood is loaded with a vertical pull and a shear force. It is fixed in the two upper
corners. Dimensions: Height 15.0, width 20.0, and depth 15.0. </p>
