ME 355 — Strength of Materials II
BSc BSc Agricultural Engineering · Kwame Nkrumah University of Science and Technology
Objectives As students complete this course, should be able to provide the concepts, procedures, data, and decision analysis techniques; design machine elements commonly found in mechanical devices and systems and execute original designs for machine elements integrate the elements into a system composed of several elements. Content Design of Mechanical Elements I, the concepts of ME 174 and ME 274 are applied to the analysis, selection, and design of specific mechanical elements such as shafts, fasteners, weldments, springs, rolling contact bearings, film bearings, and power screws. Shafts and Shaft Components: Introduction; Shaft Materials; Shaft Layout; Shaft Design for Stress, Deflection and Critical Speeds; Miscellaneous Shaft Components. Rolling-Contact Bearings: Bearing Types; Bearing Load Life and Reliability; Selection of Ball and Cylindrical Roller and Tapered Roller Bearings; Design Assessment for Selected RollingContact Bearings; Lubrication; Mounting and Enclosure. Lubrication and Journal Bearings: Types of Lubrication: Viscosity; Petroff’s Equation; Stable, Thick-Film and Hydrodynamic Lubrication Theory; The Relations of the Variables and Steady-State Conditions in Self Contained Bearings; Loads and Materials; Bearing Types. Mechanical Springs: Stresses, Curvature Effect and Deflection in Helical Springs; Spring Materials; Helical Compression Spring Design for Static Service and Fatigue Loading. Design of Permanent and Non-Permanent Joints: Thread Standards and Definitions; The Mechanics of Power Screws; Joints; Bolt Strength; Tension Joints; Fatigue Loading of Tension Joints, Bolted and Riveted Joints; Butt and Fillet Welds; Stresses in Welded Joints in Torsion; and in Bending; The Strength of Welded Joints; Static Loading; Fatigue Loading; Resistance Welding; Adhesive Bonding. Mode of Delivery The mode of delivery of this course will be blended i.e., in person and online Reading Materials Product Design by Kevin Otto & Kristin Wood, ISBN 0-13-021271-7 Design of Machine Elements by M.
