Capstone: Checking a Colleague's Results – Equilibrium, Sensitivity, Stress Utilisation
This lesson is part of the course
In this lesson
You review a colleague's hand model of a bar between two walls: recompute the displacement, test the reported reactions for equilibrium, measure the sensitivity to a 10 % smaller area and compare the stresses with a fictional allowable value.
