Column AB is a circular cross section with a radius of r, and the length L is very long compared to r. One end A of the column AB is fixed and receives a compressive load P acting on the center of B. At this time, what is the minimum radius r of the circular cross section to prevent buckling on the column AB? (However, the elastic modulus of the column AB is E.)

A steel pipe column has a length L=4.25 m and has tubular cross section with inside diameter dy=64 mm and outside diameter d2=90 mm. The column is fixed at the base and pinned at the top. The modulus of elasticity of steel is E=210 GPa. The theoretical Euler buckling load of the column is most nearly: dy dz A. 720 KN B. 560 kN C. 303 kN D. 690 KN The steel post has a length L=4 m and carries...
A cantilever beam AB with a circular cross section and length L = 750 mm supports a load P = 800 N acting at the free end (see figure). The beam is made of steel with an allowable bending stress of l20 MPa. Determine the required diameter d_min (figure part a) of the beam, considering the effect of the beam's own weight. Repeat part (a) if the beam is hollow with wall thickness t = d/8 (figure part b); compare...
A rod, in the form of a cylinder of length L and circular cross-section of radius r, has a resistance R. What is the new value of the resistance R if the length is doubled (2L) and the radius is doubled (2r)?
Problem 4. At one end of an elastic beam (length 2L, annular cross section with outer radius R, inner radius r, and planar moment of inertia z(R4- that is supported by a truss structure (cross-sectional area A), a vertical load P is applied, which results in a vertical deflection at that point that can be determined by 5PL 2PL3 EA 3EIz Two experiments with the same data but different inner radii r were conducted, and the deflections w were measured....
Looking for Help on 10.19. r of solid circular cross section is 50 mm in diameter. The bar is pinned at each end and subject to axial compression. If the proportional limit of the material is 210 MPa and E 200 GPa, determine the minimum length for which Euler's formula is valid. Also, determine the value of the Euler buckling load if the column has this minimum length. Ans. 1.21 m, 412 kN 10.20. The column shown in Fig. 10-10...
A2 m long column made of structural steel with elastic modulus of 200 GPa is loaded in axial compression. If the cross section of the column is a 20 mm by 50 mm rectangle, and one end is fixed and the other end is pinned, the maximum axial load that the column can bear before buckling, in kN, is (round to the nearest whole number)
