To determine The stress components acting on the inclined plane AB using the method of equilibrium. Explanation Let the sectioned area be Δ A and the adjacent areas of the segment be Δ A sin θ and Δ A cos θ . Sketch of the arbitrary section of the lower segment of the element is shown in Figure 1. The force acting on each segment can be obtained by multiplying the stress components on each face by the area upon which the stress acts. Let the normal and shear stress components acting on the + x ' face of the element be σ x ' and τ x ' y ' . Let the sectioned force in the y ' face be Δ F y ' and the sectioned force in the x ' face be Δ F x ' . Draw the free body diagram of the segment showing the force that acting on the segment as in Figure 2. Calculation: Apply Equilibrium equations to the free body diagram of the segment. Sum of forces in the y ' face of the element is equal to 0. ∑ F y ' = 0 [ Δ F y ' − ( 8 Δ A sin 40 ° ) sin 40 ° − ( 5 Δ A sin 40 ° ) sin 50 ° + ( 3 Δ A cos 40 ° ) sin 40 ° + ( 8 Δ A cos 40 ° ) sin 50 ° ] = 0 Δ F y ' = − 0.4044 Δ A Sum of forces in the x ' face of the element is equal to 0. ∑ F x ' = 0 [ Δ F x ' + ( 8 Δ A sin 40 ° ) cos 40 ° − ( 5 Δ A sin 40 ° ) cos 50 ° − ( 3 Δ A cos 40 ° ) cos 40 ° + ( 8 Δ A cos 40 ° ) cos 50 ° ] = 0 Δ F x ' = − 3

Stress transformation

The term stress indicates the measure of internal forces that develop due to an external force's application on an object. When a specific external force is applied to an object, internal stress generates in the material. The value of stress can obtain b…
