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 load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

Question

I am trying to find the internal force and strain of section (2) of the bar, how do I solve this?

A downward load of Q = 36 kN is applied to rigid bar ABD as shown in the sketch. Axial member CDE is subjected to a downward load
of P = 25 kN at joint E plus a force at joint D from the rigid bar. The axial member has an elastic modulus of E= 65 GPa and a cross-
sectional area of A₁ - A₂ = 125 mm². Assume that a = 420 mm, b = 220 mm, c = 660 mm, and d = 445 mm. Determine the vertical
displacement of joint E.

Please show the formula used and free body diagram A rectangular steel block is 4 inches long in the x direction, 3 inches long in the y direction, and 4 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 48 kips tension in the x direction, 60 kips compression in the y direction, and 54 kips tension in the z direction. If ν = 0.30 and E = 29 × 106 psi, determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading.

A steel torsion bar AB with diameter d = 34 mm, and ductile material of tensile yield strength Sy = 276 MPa is attached to a rigid arm at A, supported by a bearing at C, and fixed at B, as the picture shows. At the right end of the arm is mounted the wheel on which the vertical force P acts from the ground and which passes through the center of the wheel. If bearing C acts as a simple support and the effect of transverse shear due to P is negligible, determine the maximum force P (in kN) that can be applied to the wheel. Consider a factor of safety n = 2.5. Use the maximum energy of distortion failure criterion and do the analysis on bar AB (torsion bar) in the section where the bearing is.

While the ABCD rigid beam shown in the figure is simply supported from the A point, it is supported by vertical BF and CE bars from the B and C points, respectively. There is no tension in the bars in the unloaded condition. Considering that the length of the BF rod is 800 mm in addition to the given dimensions, if a strain value of -600 um / m unit occurs in the BF rod when a vertical P load is applied from the D end, the elongation amount in the CE rod will be the following in mm.
