Bending Moment

• If there is a beam attached to a wall, if force is applied to the other end of the beam that is not attahced we create a moment

• This moment is similar to torque that will force the beam to bend

• Moment or Torque = Force x Distance

• Distance in this case is the perpendicular distance (between point 1 and point 2)

• If you double the force you doulbe the moment, if you double the distance you double the moment

• Increasing distance is also called leverage

  • although leverage can also imply a non bending moment

  • internally would be bending (for the tool being used)

  • externally would be non-bending (rotation of the system)

Solve for the displacement field using minimum potential energy involving variational calculus (hmmm)
