Course Instructor

The training course will be presented by Jon Ness, PE.  Jon has over 27 years of engineering and design experience related to the development of mobile equipment components and sub-systems including dynamically loaded bolted joints.  His work has included the design of multiple gear boxes, powertrain systems, engine installations, and the development of test and validation plan strategies.   He has taught numerous classes related to Failure Modes and Effects Analysis and Bolted Joint Design for design engineers.

The course represents 14 Professional Development Hours (PDH).
