The right leg of an athlete on a rowing machine can be modeled as a linkage as shown, where A represent the ankle (which is stationary), K the knee, and H the hip. At the instant when 0 = 75°, the shank AK has an angular velocity of 1 rad/s and an angular acceleration of 1.45 rad/s2, both counter-clockwise. Determine the velocity and acceleration of the hip Hat this instant in time. H 442 mm 310 mm 375 mm 0 O A Xconcept 2

The instant shown, bar AB has an angular velocity of 6.5 rad/s and an angular acceleration of 4 rad/s², both clockwise. 200 mm B 75 mm D 175 mm 100 mm A E Determine the angular acceleration of bar BD by using the vector approach. (You must provide an answer before moving to the next part.) The angular acceleration of bar BD is rad/s² clockwise.
