The folders at the links below contain all of the parts and assemblies that are needed for the opening the two mechanisms in SolidWorks.
There is one assembly per mechanism which contain the links to the various parts that make up that assembly.  You need the parts also.  To access these files in SolidWorks follow the steps outlined below:

• Somewhere on your own computer's C: drive create two folders (in My Documents or on your Desktop) :
• Sarrus
• Bevel Gears
• Click on the links below.
• Save each zip file to the specific folder created in the step above.
• "Extract" the zip file in the same folder.
• It is important that all of the part files and the assembly file are 'extracted" to the same folder.
• When done, startup SolidWorks then open the sarrus.sldasm or bevelgears.SLDASM assembly files.
• The assemblies will look for the parts in the folders that the assemblies are in and will open those parts in the assembly.
• Try rotating the parts of each assembly.
