Occurs when a physical force presses inward on an object, causing it to become compacted.

• Compression
• Torsion
• Tension
• Bending

State of stress in which a material is being pulled apart.

• Tension
• Compression
• Torsion
• Bending

The behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element.

• Bending
• Compression
• Tension
• Torsion

Refers to the twisting of a structural member that is loaded by couples (torque) that produce rotation about the member's longitudinal axis.

• Torsion
• Compression
• Tension
• Bending

Measure of the capacity or ability of the force to produce twisting or turning effect about an axis.

• Moment 
• Thermal Stress
• Moment Arm 
• Stress 

Determines the degree of effectiveness or influence of a force to produce or prevent the rotation of an object around an axis.

• Moment Arm 
• Moment 
• Thermal Stress
• Stress 

Ratio of applied force F to a cross section area - defined as "force per unit area".
