Final answer:
The material used, dimension, and shape of an engineering product can affect its deformation behavior when stress is applied. The elastic modulus of the material determines how it responds to stress, with a high elastic modulus indicating a material that is hard to deform and a low elastic modulus indicating a material that is easily deformed.
Step-by-step explanation:
When stress is applied to an engineering product, the material used, dimension, and shape of the product design can affect its deformation behavior. The elastic modulus of a material determines how it responds to stress. A high elastic modulus means the material is hard to deform and requires a high load to achieve a significant strain, while a low elastic modulus means the material is easily deformed under a load.
For example, let's consider a steel band and a rubber band of the same dimensions. When stress is applied to the steel band, it produces minimal strain and deformation due to its high elastic modulus. On the other hand, when stress is applied to the rubber band, it undergoes larger strain and deformation because its elastic modulus is much smaller than that of steel.
In addition to the elasticity of the material, the dimension and shape of the product also play a role in deformation behavior. For instance, a product with a thin and long shape, such as a beam, is more likely to experience bending deformation when stress is applied. On the other hand, a product with a bulky shape, such as a solid block, is more likely to experience compression or expansion deformation.
