slide2. HUMAN FACTORS ENGINEERING UNIT – 2 Physical Loading The components of physical loading: Physical Loading = posture × forces × time Posture (Space, Vision, Stress, Protective Clothing)
Good and bad posture
Factors that may influence body posture
Causes and consequences of bad posture<br>
slide3. Figure : Characteristics of good body posture (for the purpose of being ready for additional loading) or typical scenarios that people often brush of as “not so bad” or just a minor inconvenience, but which may lead to risk for injury. Good Body Posture • Feet irmly planted on the ground • Knees directly above the middle of the ankle joints • Hips directly above the knees • Shoulders squarely above the hips • Head and neck held in a way that aligns the ear directly over the shoulders<br>
slide4. Figure :The basic “neutral” posture (red), typically considered as the lowest risk for harmful loading, and a near-maximal deviation of limbs (orange) from that neutral position, generating biomechanical torque on most joints. Bending and twisting also lead to deviation from the “ideal” starting posture.<br>
slide6. Motion capture<br>
slide7. Force: Terminology concerning forces.<br>
slide8. Figure : Force gauge for measuring push and pull force. Measuring force<br>
slide9. Time :
Terminology of time exposures:
Repetitiveness
Frequency
Cycle time
Endurance time
Fatigue
Recovery
Resumption time
Cumulative loading
Variation<br>
