Which study type in Inventor Stress Analysis calculates natural frequencies and mode shapes of a part?
Answer: Modal Analysis
Modal Analysis computes natural frequencies and their associated mode shapes.
Which constraint lets a cylindrical face rotate while optionally fixing radial, axial, or tangential movement?
Answer: Pin Constraint
A Pin constraint applies to cylindrical faces and lets you fix radial, axial, and tangential directions independently.
A Frictionless constraint applied to a planar face prevents motion in which direction?
Answer: Normal to the face only
A Frictionless constraint stops movement normal to the face but allows sliding in the plane of the face.
Which load type simulates the uneven radial pressure a shaft puts on a cylindrical hole?
Answer: Bearing Load
A Bearing Load distributes force over a cylindrical face the way a shaft or pin loads a bore.
Which result type is most often compared with a ductile material's yield strength to predict failure?
Answer: Von Mises Stress
Von Mises equivalent stress is the standard failure criterion for ductile materials.
For a brittle material, Inventor calculates the Safety Factor from which property?
Answer: Ultimate tensile strength
Brittle materials have no clear yield point, so the safety factor uses ultimate tensile strength.
What does a Safety Factor below 1.0 mean in the results?
Answer: The stress exceeds the material limit at that location
A safety factor below 1 means the calculated stress is higher than the allowable strength there.
