  1. Case StudyShoulder Muscle Strengthening

  2. Case StudyShoulder Muscle Strengthening Weights: Barbell (300 N) Arm (50 N) Step I: Determine the weights and the points of interest

  3. Case StudyShoulder Muscle Strengthening B Distance measurements: a= b= b A a o Step 2:Measure the distance between the points of interest

  4. Case StudyShoulder Muscle Strengthening b a Step 3:Draw a free-body diagram

  5. Case StudyShoulder Muscle Strengthening d1 = a sin q d2 = b sin q M1= d1W1=aW1 sin q M2= d2(W2/2)=b(W2/2) sin q Mo = M1+ M2 Step 4: Determine the expressions for calculating moments.

  6. Step 5: Measure the angle for each position

  7. Case Study:Shoulder Muscle Strengthening M1= d1W1=aW1 sin q M2= d2(W2/2)=b(W2/2) sin q Mo = M1+ M2 Step 6: Substitute the values of a, b and q & solve the equations for moments

  8. Case Study IIAnother In-class ExerciseQuadriceps Muscle Strengthening Using leg images, calculate the net moment generated about the knee joint? Sample Information: Weight of Lower leg = 50N Dead weight @ ankle = 100N Link:http://tc.bme.rpi.edu/Statics/Exercise_Images/Quad Time limit = 15 minutes

  9. Case Study II (Solutions)

  10. Case Study II(Solutions) d1 = a cos q d2 = b cos q Mo = d1W1+ d2W2 = a cos qW1+ b cos q W2 = (a W1 + b W2) cos q
