EJERCICIOS RESUELTO ESTATICA – Ensayos – lauraviedma
Solution Problem A homogeneous kg bar AB is supported at either end by a cable as shown in Fig. There are two types of normal stresses; tensile stress and compressive stress.
If the force is going to pull the material, the stress is said to be tensile stress sabritsa compressive stress develops when the material is being compressed by two opposing forces.
Normal Stress Stress Stress is the expression of force applied to a unit area of surface. An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig. Indicate tension T or compression C.
Another unit of stress which is not commonly used is the dynes cgs unit. Example is the bolt that holds the tension rod in its anchor. Simple stresses are expressed as the ratio of the applied force divided by the resisting area or. Solution Problem An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig.
The cross-sectional areas of wires AB and AC are 0.
Find the stress in the cable if its diameter is 0. The maximum stress in tension or compression occurs over a section normal sabriitas the load. For the truss shown in Fig. Another type of simple stress is the bearing stress, it is the contact pressure between two bodies. Another condition of shearing is when we twist a bar along its longitudinal axis. Simple stress can be classified as normal stress, shear stress, and bearing stress. Normal Stress The resisting area is perpendicular to the applied force, thus normal.
Determine the largest weight W that can be supported by two wires shown in Fig.

Suspension bridges are good example of structures that carry these stresses. 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.
Shear stress is developed if the applied force is parallel to the resisting area. Stress is the expression of force applied to a unit area of surface. P is supported by a smooth pin at C and a cable that runs from A to B around the smooth peg at D.
The resisting area is perpendicular to the applied force, thus normal. Solution Problem A rod is composed of an aluminum section rigidly attached between steel and bronze sections, as shown in Fig.
Solution Problem For the truss shown in Fig. Stress is the ratio of force over 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. The crosssectional area of each member is 1. Stress is the lead to accurately describe and predict the elastic deformation of a body.
The suspension cables then transferred the force into bridge towers.
Normal stress develops when a force is applied perpendicular to the cross-sectional area of the material. Determine the maximum value of the load P if the stress in wood is limited to psi and that in concrete to psi. Tensile stress applied to bar tends the bar to elongate while compressive stress tend to shorten the bar.
Axial loads are applied at the positions indicated. There are three csao of simple stress namely; normal stress, ccaso stress, and bearing stress.
