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.
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
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
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
