Plot the tangent modulus and reduced modulus column curves for a column of solid circular cross-section of radius R
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.)
What is the ratio of the section modulus of a circular section A with a radius of a, a square section B with a length of one side, and a rectangular section C with a length of the base and a height of 2a?

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...

A truncated solid cone is of circular cross section, and its
diameter is related to the axial coordinate by an expression of the
formD=ax3/2, wherea=1.0 m-1/2.
The sides are well insulated, while the top surface of the cone
atx1is maintained atT1and the bottom surface atx2is maintained
atT2.
What is the rate of heat transfer across the cone if it is
constructed of pure aluminum withx1=0.075 m,T1=240°C,x2=0.225 m,
andT2=20°C? Evaluate the properties of aluminum atT¯=333 K.
