A truncated cone with a circular cross-section is suspended as shown and subjected to a force P. The Young’s modulus of the cone material is E, and the cross-sectional radius of the cone is given by the relation: rz r zL () 1 = ? o ( ) . Neglecting the weight of the cone itself, calculate the increase in length of the cone due to the applied force P.

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.)
Consider a long cylinder of circular cross-section with radius R, as shown in Fig. 3. The cross section is subjected to torque T on its ends. As you can see from the special case of a = b in the solution for the warping function of an elliptical cross-section under torsion, the warping function or out-of-plane displacement of a circular cross-section vanishes.(a) What is the maximum shear stress in the cross-section and where does it occur?(b) What is the shear stress, σθz, as a function of radius, r?
