results is the "crusher" gage. These gages employ a type of annealed copper in the form of spheres or cylinders to deter- mine the peak pressures in situations where more fragile devices would fall. One use of these gages is In the high- pressure chamber of high performance guns where the gage Is subjected to violent changes in pressure.
