When you pull on the rod at point C, the tensile force is transmitted back to the plate and nut at point B. You cannot have a tension in the tube with this arrangement of parts.influx said:
Tension is a force that pulls or stretches a material, while compression is a force that pushes or squeezes a material. In other words, tension elongates a material, while compression shortens it.
The stress in an axially loaded member can be calculated by dividing the applied force by the cross-sectional area of the member. This is known as the tensile or compressive stress, depending on the direction of the force.
The strength of an axially loaded member can be affected by various factors such as the material properties, cross-sectional area, length of the member, and the magnitude and direction of the applied force. Other factors include temperature, corrosion, and imperfections in the material.
The type of material can greatly affect the behavior of an axially loaded member. Some materials, such as steel, have high strength and stiffness, making them able to withstand large tensile or compressive forces. Other materials, like rubber, are more flexible and will deform under smaller loads. The type of material also determines its fracture behavior, which is important in predicting failure.
Axial stress is the stress caused by an axial force applied along the length of a member, while bending stress is caused by a combination of axial force and a moment applied to the member. Axial stress is uniform along the length of the member, while bending stress varies along the length, with the highest stress occurring at the point of maximum bending.
