Engineering Design & Analysis 2

These flashcards cover key concepts related to the study of thrust, shear forces, and bending moments in structural analysis, applicable to the engineering design and analysis of beams.

Axial Thrust

The force that acts along the longitudinal axis of an object or structure.

Shear Force

The force that acts perpendicular to the longitudinal axis of an object, causing it to shear.

Bending Moment

The moment that causes a beam to bend, defined as the sum of the moments about a given point.

2 Dimensional Equilibrium

A condition where the sum of all forces and the sum of all moments acting on a body are zero.

Simply-supported Beam

A beam supported at its ends by supports that allow it to move freely; no moments are developed at the supports.

Cantilever Beam

A beam that is fixed at one end and free at the other, allowing for overhanging loads.

Point Load

A load that is applied at a single point on a beam.

Uniformly Distributed Load (UDL)

A load that is spread evenly over a length of a beam.

Thrust Diagram

A diagram that represents the axial thrust along the length of a beam.

Shear Force Diagram (SFD)

A diagram that shows how shear force varies along the length of a beam.

Bending Moment Diagram (BMD)

A diagram that illustrates how the bending moment changes along the length of a beam.

Contraflexure

The point along the beam where the bending moment is zero, indicating a change in the curvature of the beam.

Knife Edge Support

A type of support that allows rotation but no translation, acting like a pin.

Reaction Force

The force exerted by supports in response to applied loads.

Maximum Shear Force

The peak value of shear force experienced along a beam under loading.

Maximum Bending Moment

The highest value of bending moment that occurs along a beam due to applied loads.

Sign Conventions

Agreed upon rules used to define the direction of forces and moments in structural analysis.

Equilibrium of Beams

The state where the sum of vertical forces, horizontal forces, and moments about any point equals zero.
