If the solution of the equilibrium equations yields a negative value for a resultant, the assumed directional sense of the resultant is opposite to that shown on the free-body diagram. These changes are referred to as deformation, and they may be either highly visible or practically unnoticeable.

For example, a rubber band will undergo a very large deformation when stretched, whereas only slight deformations of structural members occur when a building is occupied by people walking about. Deformation of a body can also occur when the temperature of the body is changed.

A typical example is the thermal expansion or contraction of a roof caused by the weather. In a general sense, the deformation of a body will not be uniform throughout its volume, and so the change in geometry of any line segment within the body may vary substantially along its length.

Hence, to study deformational changes in a more uniform manner, we will consider line segments that are very short and located in the neighborhood of a point. Realize, however, that these changes will also depend on the orientation of the line segment at the point.

For example, a line segment may elongate if it is oriented in one direction, whereas it may contract if it is oriented in another direction. Strain is actually measured by experiments, and once the strain is obtained, it will be shown in the next chapter how it can be related to the stress acting within the body. We have also shown that the mathematical relationship between stress and strain depends on the type of material from which the body is made.

Torsional Deformation of a Circular Shaft : Torque is a moment that tends to twist a member about its longitudinal axis. Its effect is of primary concern in the design of axles or drive shafts used in vehicles and machinery. We can illustrate physically what happens when a torque is applied to a circular shaft by considering the shaft to be made of a highly deformable material such as rubber.

When the torque is applied, the circles and longitudinal grid lines originally marked on the shaft tend to distort into the pattern shown in. Note that twisting causes the circles to remain circles, and each longitudinal grid line deforms into a helix that intersects the circles at equal angles.

Also, the cross sections from the ends along the shaft will remain flat—that is, they do not warp or bulge in or out—and radial lines remain straight during the deformation. From these observations we can assume that if the angle of twist is small, the length of the shaft and its radius will remain unchanged. Angle of Twist : Occasionally the design of a shaft depends on restricting the amount of rotation or twist that may occur when the shaft is subjected to a torque.

Furthermore, being able to compute the angle of twist for a shaft is important when analyzing the reactions on statically indeterminate shafts. Critical Load : Whenever a member is designed, it is necessary that it satisfy specific strength, deflection, and stability requirements.

Some members, however, may be subjected to compressive loadings, and if these members are long and slender the loading may be large enough to cause the member to deflect laterally or sidesway. To be specific, long slender members subjected to an axial compressive force are called columns, and the lateral deflection that occurs is called buckling.

Establish the x, y, z coordinate axes with origin at the centroid and show the resultant internal loadings acting along the axes.

Equations of Equilibrium. Moments should be summed at the section, about each of the coordinate axes where the resultants act. Doing this eliminates the unknown forces N and V and allows a direct solution for M and T.

If the solution of the equilibrium equations yields a negative value for a resultant, the assumed directional sense of the resultant is opposite to that shown on the free-body diagram. These changes are referred to as deformation, and they may be either highly visible or practically unnoticeable.

For example, a rubber band will undergo a very large deformation when stretched, whereas only slight deformations of structural members occur when a building is occupied by people walking about.

Realize, however, that these changes will also depend on the orientation of the line segment at the point. For example, a line segment may elongate if it is oriented in one direction, whereas it may contract if it is oriented in another direction.

In order to describe the deformation of a body by changes in length of line segments and the changes in the angles between them, we will develop the concept of strain.

Strain is actually measured by experiments, and once the strain is obtained, it will be shown in the next chapter how it can be related to the stress acting within the body.

In the previous chapters, we have developed the concept of stress as a means of measuring the force distribution within a body and strain as. We have also shown that the mathematical relationship between stress and strain depends on the type of material from which the body is made.

To be specific, long slender members subjected to an axial compressive force are called columns, and the lateral deflection that occurs is called buckling. Quite often the buckling of a column can lead to a sudden and dramatic failure of a structure or mechanism, and as a result, special attention must be given to the design of columns so that they can safely support their intended loadings without buckling.
