Grain structure of metals is not affected by plastic strain such as making wire. T or F 4. The mechanical behavior of all materials is affected by temperature. T or F 5. Elastic deformation does not change the arrangement of atoms in materials. T or F б. Materials that show plastic deformation are ductile. T-or F 7. A true elastic behavior reaches an instantaneous yield point. T or E Repeated loadings may create stresses that are less than the strength of the material which leads to "fatigue failure." 8.arrow_forward
- A uniform beam of weight Wis supported by the two rods, the lower ends of which are at the same level just before the beam is supported, as shown in figure.

- There is no force on a beam, but the beam is subjected to a very large temperature difference above and below. As shown in the figure below, try to calculate the vertical displacement of the midpoint of the beam, assuming that the temperature coefficient of the entire beam is a = 11.7×10^-6 °F. Tip: See Mechanics of Materials for Beam Deformation Geometryarrow_forwardAn elastic bar of length L, uniform cross sectional area A, coefficient of thermal expansion a and Young's modulus E is fixed at the two ends. The temperature of the bar is increased by T, resulting in an axial stress o. Keeping all other parameters unchanged, if the length of the bar is doubled, the axial stress would bearrow_forwardThe state of strain of the element has components of €x = 500(106), y = 300(106), Yxy=-200(10-6).
