  4. Increases stiffness

Questions & Step-by-Step Solutions

In a beam subjected to a moment, what is the effect of increasing the moment of inertia (I) on the deflection?
  • Step 1: Understand what a beam is. A beam is a structural element that supports loads.
  • Step 2: Know what a moment is. A moment is a force that causes the beam to bend.
  • Step 3: Learn about moment of inertia (I). It is a property of the beam that measures how resistant it is to bending.
  • Step 4: Recognize that deflection is how much the beam bends under a load.
  • Step 5: Realize that if you increase the moment of inertia (I), the beam becomes stiffer.
  • Step 6: Understand that a stiffer beam will bend less under the same load, meaning the deflection decreases.
