Simulation problem
Problem Type
Plane-parallel problem of stress analysis.
Wrench thickness d = 10 mm;
Force applied f = 100 N;
Young's modulus E = 200 GPa;
Poisson's ratio ν = 0.33.
Calculate the wrench hand displacement.
In QuickField we specify the force-per-depth value, that is f = f / d = 100 / 0.01 = 10 kN/m.
The wrench hand will move for 9 mm.
