Applied Statics Concepts: Applied Statics And Strength Of Materials 6th Edition Answer Key
Applied statics is the branch of mechanics that deals with the analysis of forces acting on bodies at rest. The fundamental principles of statics are used to solve a wide variety of engineering problems, such as determining the forces and moments acting on structures, machines, and vehicles.
Examples of real-world applications where statics principles are utilized include:
- The design of bridges and buildings to withstand the forces of gravity, wind, and earthquakes
- The analysis of forces acting on aircraft wings to ensure safe and efficient flight
- The design of automotive suspension systems to provide a comfortable ride and good handling
The different types of forces and moments that can act on structures include:
- Forces: Forces are vectors that have both magnitude and direction. They can be applied to a body at any point.
- Moments: Moments are vectors that have both magnitude and direction. They are applied to a body about a specific point or axis.
Strength of Materials Analysis
Strength of materials is the branch of mechanics that deals with the analysis of the behavior of materials under the action of forces. The concepts of stress, strain, and elasticity are fundamental to strength of materials analysis.
Stress is a measure of the internal forces acting on a material. Strain is a measure of the deformation of a material. Elasticity is a measure of the ability of a material to return to its original shape after being deformed.
The different types of material failure modes include:
- Tensile failure: Tensile failure occurs when a material is subjected to a force that pulls it apart.
- Compressive failure: Compressive failure occurs when a material is subjected to a force that pushes it together.
- Shear failure: Shear failure occurs when a material is subjected to a force that causes it to slide in one direction relative to another.
- Bending failure: Bending failure occurs when a material is subjected to a force that causes it to bend.
- Torsional failure: Torsional failure occurs when a material is subjected to a force that causes it to twist.
The methods used to determine the strength of materials under various loading conditions include:
- Tensile testing: Tensile testing is a method used to determine the tensile strength of a material.
- Compressive testing: Compressive testing is a method used to determine the compressive strength of a material.
- Shear testing: Shear testing is a method used to determine the shear strength of a material.
- Bending testing: Bending testing is a method used to determine the bending strength of a material.
- Torsional testing: Torsional testing is a method used to determine the torsional strength of a material.
Structural Analysis Techniques
Structural analysis is the branch of mechanics that deals with the analysis of the behavior of structures under the action of forces. The principles of structural analysis are used to design structures that are safe and efficient.
The different methods used to analyze structures include:
- The method of sections: The method of sections is a method used to analyze the forces and moments acting on a structure by cutting it into sections.
- The method of joints: The method of joints is a method used to analyze the forces and moments acting on a structure by considering the equilibrium of each joint.
- The method of virtual work: The method of virtual work is a method used to analyze the forces and moments acting on a structure by considering the virtual work done by the forces.
The different methods used to calculate deflections and stresses in structures include:
- The slope-deflection method: The slope-deflection method is a method used to calculate the deflections and stresses in a structure by considering the slopes and deflections of the members.
- The moment-distribution method: The moment-distribution method is a method used to calculate the deflections and stresses in a structure by considering the distribution of moments at the joints.
- The finite element method: The finite element method is a method used to calculate the deflections and stresses in a structure by dividing it into a number of small elements.
Applied Examples and Case Studies
Applied examples and case studies are essential for understanding how statics and strength of materials principles are applied in engineering practice. The following are a few examples of how these principles are used in the design and analysis of structures:
- The design of the Golden Gate Bridge: The Golden Gate Bridge is a suspension bridge that spans the Golden Gate strait in San Francisco, California. The bridge was designed to withstand the forces of gravity, wind, and earthquakes.
- The analysis of the World Trade Center towers: The World Trade Center towers were two of the tallest buildings in the world. The towers were designed to withstand the forces of gravity, wind, and earthquakes. However, the towers collapsed after being struck by airplanes on September 11, 2001.
- The design of the Boeing 777: The Boeing 777 is a wide-body jet airliner. The aircraft was designed to withstand the forces of gravity, wind, and turbulence.
