Finding flexural compressive stress and tensile stress

In summary, to find the maximum flexural compressive and tensile stresses, you would need to use a shear force diagram and a bending moment diagram. These diagrams represent forces and moments, not stresses. To obtain stresses, you would also need to know the cross section characteristics. Yes, the peaks on the diagrams indicate the maximum stresses. It is also possible to determine shear stress from these diagrams.

How would I use a shear force diagram and a bending moment diagram to find the maximum flexural compressive stress and the maximum flexural tensile stress?


I am assuming the peaks at the bending moment diagram is the maximum tensile and compressive stresses? Am I correct?

Also, is it possible to determine the shear stress from a shear force diagram or a bending moment diagram?

Shear force and bending moment diagrams represent quantities of forces and moments, respectively. Forces and moments are not stresses. A bit simplified answer is that stress is the force per unit area. So, if you have some force diagrams, you need to know some cross section characteristics in order to obtain stresses. And, of course, yes, you usually look for the stresses at the points which are peaks of force diagrams.

What is flexural compressive stress and tensile stress?

Flexural compressive stress is the amount of compressive force per unit area that a material can withstand before it fails. Tensile stress, on the other hand, is the amount of tensile force per unit area that a material can withstand before it fails. These two types of stress are important in determining the strength and stability of a material.

How do you calculate flexural compressive stress and tensile stress?

Flexural compressive stress can be calculated by dividing the maximum compressive force applied to a material by its cross-sectional area. Tensile stress can be calculated by dividing the maximum tensile force applied to a material by its cross-sectional area. Both values are typically expressed in units of force per unit area, such as pounds per square inch (psi) or newtons per square meter (N/m²).

What factors can affect flexural compressive stress and tensile stress?

The type of material, its composition, and its structure can all affect its flexural compressive stress and tensile stress. Other factors that can influence these values include temperature, rate of loading, and the presence of defects or flaws in the material.

Why is it important to determine flexural compressive stress and tensile stress?

Knowing the flexural compressive stress and tensile stress of a material is crucial in determining its strength and durability. It allows engineers to design structures and products that can withstand the expected forces and stresses they will encounter, ensuring their safety and reliability.

How can flexural compressive stress and tensile stress be applied in real-world situations?

Flexural compressive stress and tensile stress calculations are commonly used in engineering and construction projects. They are also important in the design of everyday objects, such as furniture, appliances, and vehicles. In the field of materials science, these values are used to compare the strength and stability of different materials and to identify their potential applications.
