What is the relation between load and stress?

Stress is the internal resistance, or counterforce, of a material to the distorting effects of an external force or load. These counterforces tend to return the atoms to their normal positions. The total resistance developed is equal to the external load. This resistance is known as stress.

When an external force is applied on a body an internal resistance is developed inside the body?

When an external force is applied on a body, internal resistance is developed within the body to balance the effect of externally applied forces. The resistive force per unit area is called as stress.

Is stress a resistance force?

Stress is the resistance force per unit area offered by a body against deformation. In other words it is the ratio of the resistance force to the cross-section area of the body.

Is load and stress the same thing?

Load tests help you understand how a system behaves under an expected load. Stress tests help you understand the upper limits of a system’s capacity using a load beyond the expected maximum.

When a body offers resistance to deformation when acted by external load is called?

stress. Explanation: Whenever some external system of forces acts on a body, it undergoes some deformation the body undergoes some deformation, it sets up some resistance to the deformation. This resistance per unit area to deformation, is called stress.

How are external forces related to internal forces?

An external force occurs as a result of interaction between a system and the surroundings. On the other hand, an internal force is an interaction that exists within a system. External forces cause motion in an object, whereas an internal force resists the motion.

When work is done on a body by an external force it?

When work is done by external forces (nonconservative forces), the total mechanical energy of the object is altered. The work that is done can be positive work or negative work depending on whether the force doing the work is directed opposite the object’s motion or in the same direction as the object’s motion.

Which stress comes when there is an eccentric load applied?

Which stress comes when there is an eccentric load applied? Explanation: When there is an eccentric load it means that the load is at some distance from the axis. This causes compression in one side and tension on the other. This causes bending stress.

What is stress force?

Stress is the force per unit area on a body that tends to cause it to change shape. In SI units, force is measured in newtons and area in square metres. This means stress is newtons per square meter, or N/m2. However, stress has its own SI unit, called the pascal. 1 pascal (symbol Pa) is equal to 1 N/m2.

What are the differences between load stress and performance tests?

Load Testing is a type of software testing which determines the performance of a system, software product or software application under real life based load conditions….Difference between Performance Testing and Load Testing:

Performance Testing	Load Testing
It checks the behavior of the system under normal load.	It checks the behavior of the system under extreme load.

What are stress and load tools?

Load testing is used to test web-based and client-server types of application. Stress testing tests suddenly increased traffic of the application. WebLOAD, LoadView, LoadRunner, SmartMeter.io, and LoadUI NG Pro are some of the load testing tools which help us to perform load testing on the applications.

Why does the maximum stress increase when the load is applied gradually?

As the bar has stopped moving (extending) all the stored energy will be in the form of strain energy so This proves that the maximum stress induced in a body due to suddenly applied load is twice the stress induced when the same load is applied gradually. Why does the cantilever beam have a maximum bending moment on its support?

What is the difference between sudden load and gradually applied load?

When load is applied gradually it is assumed that equilibrium between internal force and applied force is maintained all the time till we reach the final value of applied load and corresponding deformation. Whereas when sudden load is applied the equilibrium is not maintain except at one point during deformation.

What is the slope of the stress-strain diagram?

The slope of the straight-line portion of the stress-strain diagram is called the Modulus of Elasticityor Young’s Modulus. E = σ/ε (normal stress – strain) G = τ/γ (shear stress – strain)

What is modulus of elasticity in stress strain diagram?

⇒ Modulus of Elasticity – Slope of the initial linear portion of the stress-strain diagram. The modulus of elasticity may also be characterized as the “stiffness” or ability of a material to resist deformation within the linear range. (Steel) ≈ 30 x 106 psi (Aluminum) ≈ 10 x 106 psi
