Jane carries a heavy object with two different body positions.
The weight of the object is 206 , and the weight of upper body is
447 N. In the first position she is upright so that the moment arm
of her upper body is 1 cm and the moment arm of the object is 25
cm. In the second position she is rounded forward so that the
moment arm of her upper body is 17 cm and the moment arm of the
object is 46 cm.
What is the total torque about the lumbosacral joint in position
one? Nm

Leigh is doing a knee extension exercise using a 100 N weight strapped to her ankle 40 cm from her knee joint. She holds her leg so that the horizontal distance from her knee joint to the weight is 30 cm. 1) What is the moment arm of the weight about the knee joint axis? 2) For this position, what torque is created by the ankle weight about her knee joint axis? 3) If the moment arm of the knee...

1. The moment of inertia (sometimes referred to as a “swing weight”) is a measure of the resistance to rotation about a particular axis. It is often expressed as Ia = mka2 where m is the mass of the object and ka is the radius of gyration about the axis of rotation. The radius of gyration ka for the arm about its COM = 0.368*(arm length). Compute the moment of inertia of the arm in the extended position about its...

To understand two different techniques for computing the torque on an object due to an applied force.Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F⃗ lies in the xy plane, and this force of magnitude F acts on the object at a point in the xy plane. The vector r⃗ is the position vector relative to the pivot point p to the point where F⃗ is applied.The torque on the...

PROBLEM 2 Knee Extension - The angular motion of the lower leg about the knee joint, and the forces and torques produced by the muscles crossing the knee joint during knee flexions and extensions have been investigated by a number of researchers utilizing different experimental techniques. One of these techniques is discussed here. Consider the person illustrated in Fig. 10.12. The test subject is sitting on a table, with the back placed against a back rest and the lower legs...

Definitions and Equations: Moment of Inertia (D): Tendency to resist angular acceleration; the angular equivalent of mass. In practical terms it is a measure of how hard it is to rotate an object or segment, like a baseball bat or a body segment. It is the sum of the products of the mass (m) with the square of its distance from the axis of rotation (ka). SEE FINAL TWO PAGES OF THIS LAB EOR CHARTS NEEDED TO CALCULATE L. 1...
