Example is the bolt that holds the tension rod in its anchor. Stress is the expression of force applied to a unit area of surface. For the truss shown in Fig.
The cross-sectional areas of wires AB and AC are 0. Normal stress develops when a force is applied perpendicular to the cross-sectional area of the material.

There are three types of simple stress namely; normal stress, shearing stress, and bearing stress. Normal Stress Stress Stress is the expression of force applied to a unit area of surface.
Another unit of stress which is not commonly used is the dynes cgs unit. P is supported by a smooth pin at C and a cable that runs from A to B around the smooth peg at D. There are two types of normal stresses; tensile stress and compressive stress. The weight of the vehicle is carried by the bridge deck and passes the force to the stringers vertical cableswhich in turn, supported by the main suspension cables.
Indicate tension T or compression C. The resisting area is perpendicular to the applied force, thus normal. Leer documento completo Guardar. Simple stresses are expressed as the resueto of the applied force divided by the resisting area or. If the force sabrltas going to pull the material, the stress is said to be tensile stress and compressive stress develops when the material is being compressed by two opposing forces.
Solution Problem A homogeneous kg bar AB is supported at either end by a cable as shown in Fig. Suspension bridges are good example of structures that carry these stresses.
Simple stress can be classified as normal stress, shear stress, and bearing stress. This type of shearing is called torsion and covered in Chapter 3.

Shear stress is developed if the applied force is parallel to the resisting area. Stress is the lead to accurately describe and predict the elastic deformation of acso body. Tensile stress applied to bar tends the bar to elongate while compressive stress tend to shorten the bar.
Solution Problem A inches square steel bearing plate lies between an 8-inches diameter wooden post and a concrete footing as shown in Fig. Stress is the ratio of force over area. Axial loads are applied at the positions indicated.
Determine the largest weight W that can be supported by two wires shown in Fig. Solution Problem An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig. Another type of simple stress is the bearing stress, it is the contact pressure between two bodies. A inches square steel bearing plate lies between an 8-inches diameter. Solution Problem A rod is composed of an aluminum section rigidly attached between steel and bronze sections, as shown in Fig.
The crosssectional area of each member is 1. An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig. Find the stress in the cable if its diameter is 0. Normal Stress The resisting area is perpendicular to the applied force, thus normal. Solution Problem For the truss shown in Fig.
The maximum stress in tension or compression occurs over a section normal to the load. Another condition of shearing is when we twist a bar along its longitudinal axis.
The stress in either wire is not to exceed 30 ksi.
