Rezuelto the force is 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. Another unit of stress which is not commonly used is the dynes cgs unit.
For the truss shown in Fig. Suspension bridges are good sabritae of structures that carry these stresses. Another condition of shearing is when we twist a bar along its longitudinal axis.
Simple stresses are expressed as the sabrihas of the applied force divided by the resisting area or. Tensile stress applied to bar tends the bar to elongate while compressive stress tend to shorten the bar. Normal Stress Stress Stress is the expression of force applied to a unit area of surface.
P is supported cas a smooth pin at C and a cable that runs from A to B around the smooth peg at D.

Example is the bolt that holds the tension rod in its anchor. An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig. Solution Problem An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig.
There are three types of simple stress namely; normal stress, shearing stress, and bearing stress.

Normal Stress The resisting area is perpendicular to the applied force, thus normal. Indicate tension T or compression C. The suspension cables then transferred the force into bridge towers. A inches sabriras 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.

Find the stress in the cable if its diameter is 0. There are two types of normal stresses; tensile stress and compressive stress. Shear stress is developed if the applied force is parallel to the resisting area.
Solution Problem A inches square steel bearing plate lies between an 8-inches diameter wooden post and a concrete footing as shown in Fig. The stress in either wire is not to exceed 30 ksi. Solution Problem For the truss shown in Fig.
Determine the largest weight W that can be supported by two wires shown in Fig. Another type of simple stress is the bearing stress, it is the contact pressure between two bodies. Stress is the expression of force applied to a unit area of surface. The resisting area is perpendicular to the applied force, thus normal.
Axial loads are applied at the positions indicated. Stress is the ratio of force over area. The crosssectional area of each member is 1. 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. 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 sabrutas suspension cables. Determine the maximum value of the load P if the stress in wood is limited to psi and that in concrete to psi.

Leer documento completo Guardar. Normal stress develops when a force is applied perpendicular to the cross-sectional area of the material. Stress is the lead to accurately describe and predict the elastic deformation of a body.
Solution Problem A homogeneous kg bar AB is supported at either end by a cable as shown in Fig. The cross-sectional areas of wires AB and AC are 0. The maximum stress in tension or compression occurs over a section normal to the load.
