What is the relative angle (in degrees) of the knee if the hip joint center is (1.14, 0.79), the knee joint center is (1.17, 0.51), and ankle joint center is (1.10, 0.08). .

Solutions

Expert Solution

The cordinates of hip joint center = (1.14,0.79)

knee joint center = (1.17,0.51)

ankle joint center = (1.10,0.08)

and are unit vectors along the x and y - axis.

The vector joining knee joint center and hip joint center() = (1.14-1.17)+(0.79-0.51)

= 0.03 + 0.28

The vector joining knee joint center and ankle joint center() = (1.10-1.17) + (0.08 - 0.51)

= -0.07 -0.43

Angle between and =

Acrylic bone cement is sometimes used in hip and knee replacements to secure an artificial joint in place. The force required to break an acrylic bone cement bond was measured for eight specimens, and the resulting mean and standard deviation were 306.01 newtons and 41.92 newtons, respectively. Assuming that it is reasonable to believe that breaking force has a distribution that is approximately normal, use a 95% confidence interval to estimate the mean breaking force for acrylic bone cement.
