Consider a structure consisting of three bars joined in a vertical line hanging from a top support.
Question:
(a) Write down the equilibrium equations for this system when only forces and displacements in the vertical direction are allowed, i.e., a onedimensional structure. Is the problem statically determinate, statically indeterminate or unstable? If the latter, describe all possible mechanisms and the constraints on the forces required to maintain equilibrium.
(b) Answer part (a) when the structure is two- dimensional, i.e., is allowed to move in a plane.
(c) Answer the same question for the fully three- dimensional version.

I am a retired teacher with 6 years of experience teaching various science subjects to high school students and undergraduate students. This background enables me to be able to help tutor students who are struggling with the science of business component of their education. Teaching difficult subjects has definitely taught me patience. There is no greater joy for me than to patiently guide a student to the correct answer. When a student has that "aha!" moment, all my efforts are worth it.
The Common Core standards are a useful yardstick for measuring how well students are doing. My students consistently met or exceeded the Common Core standards for science. I believe in working with each student's individual learning styles to help them understand the material. If students were struggling with a concept, I would figure out a different way to teach or apply that concept. I was voted Teacher of the Year six times in my career. I also won an award for Innovative Teaching Style at the 2011 National Teaching Conference.
