Example Problem $6-3$

Specify a suitable diameter of a solid, round cross section for a machine link if it is to carry $4450$ Kg of axial compressive load. The length will be $75$ cm $,$ and the ends will be pinned. Use a design factor of $2.$ Use SAE $1020$ hot$-$rolled steel

Example Problem $6-4$

A column has both ends pinned and has a length of $50$ cm $.$ It has a circular cross section with a diameter of $2$ cm and an initial crookedness of $0\mathrm{.}10$ cm $.$ The material is SAE $1040$ hot$-$rolled steel. Compute the allowable load for a design factor of $4.$

Example Problem $6-5$

For the column of Example Problem $6-4,$ compute the maximum stress and deflection if a load of $500$ Kg is applied with an eccentricity of $2$ cm $.$ The column is initially straight.

Example Problem $6-6$

The stress in the column found in Example Problem $6-5$ seems high for the SAE $1040$ hot$-$rolled steel. Redesign the column to achieve a design factor of at least $4.$
