To determine The compressive stress σ y that cause failure. Explanation Given information: The shear stress acting along the grain is 550 psi. The Normal stress is σ x = 400 psi . Calculation: Sketch the orientation and the stresses on the sectioned element as shown in Figure 1. The angle θ is positive if it curls in the counterclockwise direction. Therefore, the value of θ is 148 ° . The expression for shear stress ( τ x ' y ' ) using the stress transformation equation is shown below: τ x ' y ' = − σ x − σ y 2 sin 2 θ + τ x y cos 2 θ (1) Substitute 550 psi for τ x '

Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial …

Problem (14): A pump is being used to lift water from an underground tank through a pipe of diameter (d) at discharge (Q). The total head loss until the pump entrance can be calculated as (h₁ = K[V²/2g]), h where (V) is the flow velocity in the pipe. The elevation difference between the pump and tank surface is (h).
