There are six independent stress components shown in a conventient Cartesian coordinate system. This graphical representation of the 2-D stress transformation equations provides a quick, accurate and visual protrayal of the 2-D state of stress. They are sx, txy and sy, tyx. The same is true in 3-D stress. Arquivos Semelhantes Anamnese Exemplo de anamneses. Note also that there is one dominant peak shear stress in this diagram.

This enlarges the outermost circle which means that the overall state of stress has increased. However, there is a highly significant factor in mechanical design that has thus far been neglected.

This convention is useful for determining the proper orientation estruccturas principal stresses and other components relative to the x,y coordinates.

Sketch the normal stress, s, and shear stress, t axes and plot the coordinate pair sx, txy at point A and then sy, tyx at point B. In the real world of applications all objects are 3-D. Look at the modified estructurs below. Simple geometric triangles can then determine the circle radius and all principal stress and peak shear stress values. Then plot the second pair 0, tyx at point B. Then plot the first coordinate pair sx, txy at point A. That factor is the influence of the additional 3-D stress components on the design safety.

Determine the force in each member of the truss and state if the members are in tension or compression. Joint C: Fig a. Joint D: Joint B: Solving Ans. Support Reactions. Referring to the FBD of the entire truss, Fig. Joint A: Joint H: Joint F: Joint G: Joint E: Determine the force in each member of the truss. Indicate if the members are in tension or compression.

Assume all members are pin connected. Method of Joints: In this case, the support reactions are not required for determining the member forces.

Thus, Ans. The support reactions Ax and Ay can be determined by analyzing Joint A using the results obtained above. State whether the members are in tension or compression.

Thus, Joint E: From the above analysis, the maximum compression and tension in the truss members is 1. For this case, compression controls which requires Ans. If the maximum force that any member can support is 8 kN in tension and 6 kN in compression, determine the maximum force P that can be supported at joint D. State if the members are in tension or compression. State if the members are in tension or comprehension.
