What is the opposite of elastic?
The opposite of elastic is inelastic, where a material cannot stretch and rebound. A material without this quality could be "inflexible" (rigid, stiff) or one that did not rebound, termed "plastic" (deformable).Elastic suggests that the material recovers its original shape after an applied load is removed. Plastic means that it doesn't recover its shape. Steel is an example of an elasticmaterial, when it is loaded within its capacity. It becomes plastic if it is overloaded. Concrete can be considered an elastic material only in compression.
What is an Elastic foundation?
An elastic foundation is a foundation that is not rigid and follows Hook's law. The implications of an analysis on an elastic foundation are that you can no longer assume zero deflection from at the base of loaded structures.
What is the relation between elastic modulus and tensile modulus?
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
What is strain hardening?
When ductile material is loaded, when stress reaches yield and if the load continues, as long as load is not high enough to break material, the material is strain hardened when returning to no load. That means its yield strength will be higher than before, and the material is stronger.
Why do engineers use reinforced concrete?
Concrete is a material which is extremely effective when loaded in compression, yet performs poorly when loaded in tension. Steel on the other hand is quite effective in tension. Reinforced concrete uses steel bars wherever the concrete is loaded in tension in order to increase its capacity.

What are examples of elastic materials?
All materials are elastic to a point. An elastic material is one that returns to its original size and shape when the load that is causing it to bend or stretch, is removed. At some point all materials will exceed their "elastic limit". Mild steel used for building structures is quite elastic if not over loaded. Rubber such as a rubber band is extremely elastic but it also has an elastic limit, and an ultimate strength. Glass is not very elastic and is considered brittle.

What is strain and stress?
stress is load per unit area; when an object is loaded it is under stress and strain and it stretches (strains) until it breaks at its ultimate strength. Stress i srelated to strain in the elastic region by Hooke's law: stress = elastic modulus times strain where modulus is a property of the material and strain is deflection over length
Name the phenomenon that occurs when a etal is loded well witin the elastic range at a temperatue of 800 degrees andit slowly deforms permanently?
The phenomenon you are describing is known as creep. Creep is the slow, time-dependent deformation of a material under a constant load or stress, typically occurring at elevated temperatures. In this case, the material is being loaded within its elastic range but still deforms permanently due to the prolonged exposure to high temperature.
What is the definition of plasticity?
a substance composed predominantly of a synthetic organic high polymer capable of being cast or molded; many varieties of plastic are used to produce articles of commerce (after 1900). [MW10 gives origin of word as 1905]
When a spring is loaded the strength produced is?
When a spring is loaded, it stores potential energy due to the deformation in its structure. The strength produced by a loaded spring is related to the stiffness of the spring (measured by its spring constant) and the amount of deformation it undergoes. This stored potential energy can then be released as kinetic energy when the spring is allowed to return to its original position.
Which kind of energy does a spring-loaded popgun have?
A spring-loaded popgun stores potential energy in the form of elastic potential energy in the compressed spring. When the trigger is released, the spring expands and converts the potential energy into kinetic energy, propelling the projectile forward.
What is the weight of a 15 CY dump truck fully laden?
It depends on the density of the material that is loaded on the truck.
What is the right spring material quick release valve for steam application?
Spring loaded safety valve.
How does a rigid body differ from an elastic body?
A rigid body does not deform under stress, maintaining its shape, while an elastic body can deform under stress but will return to its original shape once the stress is removed. Rigid bodies are idealized as having infinite stiffness, while elastic bodies have finite stiffness allowing for deformation.
