Description
By (author) Philpot Timothy A.; By (author) Thomas, Jeffery S.
:
Mechanics of Materials presents the theory and practice of mechanics of materials in a straight-forward, student-friendly manner that addresses the learning styles of today”s students without sacrificing rigor or depth in the presentation of topics. From basic concepts of stress and strain to more advanced topics like beam deflections and combined loads, this book provides students with everything they need to embark on successful careers in materials and mechanical engineering. Laying an emphasis on critical thinking forms, this text focuses on helping learners develop practical skills, encouraging them to recognize fundamental concepts relevant to specific situations, identify equations needed to solve problems, and engage with literature in the field.
This International Adaptation has been thoroughly updated to use SI units. This edition strengthens the coverage by including methods such as moment area method and conjugate beam method for calculating deflection of beams, and a method for calculating shear stresses in beams of triangular cross section. Additionally, it includes Learning Assessments in a range of difficulty suitable for learners at various stages of development which elucidate and reinforce the course concepts.
