A inches square steel bearing plate lies between an 8-inches diameter. 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 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.
The suspension cables then transferred the force into bridge towers. The stress in either wire is not to exceed 30 ksi. Solution Problem A homogeneous kg bar AB is supported at either end by a cable as shown in Fig. Solution Problem An aluminum rod is sabriyas attached between a steel rod and a bronze rod as shown in Fig.
For the truss shown in Fig. P is supported by a smooth pin at C and sabrtas cable that runs from A to B around the smooth peg at D.

Simple stresses are expressed as the ratio of the applied force divided by the resisting area or. Stress is the expression of force applied to a unit area of surface. The crosssectional area of each member is 1. Example is the bolt that holds the tension rod in its anchor.
Indicate tension T or compression C. Normal Stress The resisting area is perpendicular to the applied force, thus normal. 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 casoo stress in wood is limited to psi and that in concrete to psi. The maximum stress in tension or compression occurs over a section normal to the load.
If 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 condition of shearing is when we twist a bar along its longitudinal axis.
There are three types of simple stress namely; normal stress, shearing stress, and bearing stress. Find the stress in the cable if its diameter is 0.
Another type of simple stress is the bearing stress, it is the contact pressure between two bodies. This type of shearing is called torsion and covered in Chapter 3. Axial loads are applied at the positions indicated. Simple stress can be classified as normal stress, shear stress, and bearing stress. 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.
Tensile stress applied to bar tends the bar to elongate while compressive stress tend to shorten the bar. Stress is the ratio of force over area. Suspension bridges are good example of structures that carry these stresses. Determine the largest weight W that can be supported by two wires shown in Fig. The cross-sectional areas of wires AB and AC are 0.
Stress is the lead to accurately describe and predict the elastic deformation of a body. 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 For the truss shown in Fig. 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.
