The paper reports firstly the optimization of large magnetic coils for a fusion machine of the Tokamak type. The optimization was executed with object to minimum shear stresses within the insulating glass epoxy layers which are located between the layers of the copper coil. The optimization at first followed the fully stressed design but the results did not satisfy. An examination of the influences of different mechanical details, however, led to cognitions how the feared shear stresses considerably could be reduced. The second topic introduces one problem occuring in the context with a neutron spallation source. One part of the target station is a flat containment holding pressurized water. For an improved stiffness the lid and the bottom of this containment had to be connected by rods. Sought for was the number, thickness and locations of these traverses with object to minimum deformations and stresses in the containment walls. The problem could be solved in a very agreeable way by the application of the fully stressed design.
