Week 9 - Angular Kinetics, Energetics & Static Analysis

angular impulse can graphically be viewed as area under

torque/moment vs time curve

linear impulse can graphically be viewed as area under

force vs time curve

joint moments

the net sum of all internal moments delivered by all internal structures around a joint

during loading response, what type of internal toqure is happening?

extensor torque

during loading response, where is the GRF?

posterior (creating a knee flexion moment)

during mid stance, what type of internal torque is happening?

flexor torque

during mid stance, where is the GRF?

anterior

angular work

effects of torque applied over distance

angular power

angular work done per unit time

joint power equation

net joint torque (moment) * joint angular velocity

negative value

power absorption

positive value

power reneration

joint reaction forces

how much force generated at a joint by muscles
