TA 475 T94 A TREATISE ON THE STRENGTH, FLEXURE, AND STIFFNESS OF CAST IRON BEAMS AND COLUMNS, ETC. ETC. A TREATISE ON THE STRENGTH, FLEXURE, AND STIFFNESS OF CAST IRON BEAMS AND COLUMNS, SHEWING THEIR FITNESS TO RESIST TRANSVERSE STRAINS, TORSION, COMPRESSION, WITH TABLES OF CONSTANTS, TO BE USED FOR CALCULATING THE STRENGTH, FLEXURE, and TO WHICH IS ADDED, BY WAY OF APPENDIX, A COLLECTION OF RULES IN WORDS AT LENGTH, FOR CALCULATING THE MOST IMPORTANT PRACTICAL CASES INVESTIGATED IN THE COURSE OF THE WORK, BEING INTENDED AS A GUIDE FOR BY WILLIAM TURNBULL. LONDON: JOSIAH TAYLOR, ARCHITECTURAL LIBRARY, 59, HIGH HOLBORN. 1832. PREFACE. In laying this little work before the public, the Author has to observe, that the plan of it was formed during the period of his employment with Messrs. COTTAM and HALLEN, Winsley Street, Oxford Street, London, where he had frequent occasion to direct his attention to the mode of calculating the strength and deflexion of beams and columns, of various forms and dimensions, cast by them for bearers and supports in buildings and other extensive works. To further his object in this respect, Mr. TREDGOLD's valuable Essay on the Strength of Cast Iron was put into his hand; but not having previously consulted the writings of this eminent author, the aid thus afforded was insufficient for the purpose. Mr. TREDGOLD enters largely into the detail and comparison of various practical experiments; but from a perusal of these details the writer of this work did not derive the information he wished, the 302408 |
