Biomechanics

Bone and joint biomechanics converts anatomical structures into load-bearing mechanical systems. This topic is heavily tested in B.Tech exams because it underpins implant alignment, prosthetic design, and injury-risk estimation.

Kinematics describes motion geometry, while kinetics explains forces causing that motion. This distinction is central in gait labs, sports biomechanics, and rehabilitation engineering assessments.

Biological tissues do not behave like ideal metals; they are nonlinear, anisotropic, and time dependent. This chapter asks you to interpret stress-strain curves with both mechanical and physiological context.

Gait analysis quantifies walking as a periodic biomechanical process using temporal, spatial, kinetic, and EMG features. It is widely used in rehabilitation, prosthesis tuning, and neurological assessment.

Orthopedic implant mechanics studies how artificial components share load with living bone over years of cyclic use. The chapter combines material stiffness, fixation strategy, and fatigue survival under physiological activity patterns.
