The figure below shows a human arm that weighs 39.3 N. The arm
is extended outward and is motionless. The gravitational force
Fg
on the arm acts at point A, a distance of 0.290 m from
the shoulder joint, which is represented by point O. The
shoulder pushes down and to the right on the humerus bone of the
arm with a force
Fs
at point O, at an angle θ as shown. The
deltoid muscle pulls back on the...

We wish to determine the moment at the shoulder that is required to perform the arm motion (shoulder abduction) depicted in Figure 3 below. This motion may be modelled with a simple, single- element linkage system as shown in the figure. The shoulder joint is represented by a simple pin support centred at O. The arm and the carried weight are represented as a rigid body consisting of a rod and a cuboid. In the rigid body model, the length...

3. The figure shows an outstretched arm with a mass of 4.2 kg. The arm is 56 cm long, and its center of gravity is 21 cm from the shoulder. The hand at the end of the arm hold a mass of 6.0 kg. (a) What is the torque about the shoulder due to the weights of the arm and the 6.0 kg mass? (b) If the arm is held in position by the deltoid muscle, whose force on the...

The figure below shows a shoulder exercise using a theraband. While in the posture shown, the person slowly pulls their arm down to their side while keeping the elbow straight. During this phase of the exercise the agonist muscle at the shoulder would be: a. The shoulder abductors acting concentrically b. The shoulder abductors acting eccentrically c. The shoulder adductors acting eccentrically d. The shoulder adductors acting concentrically s) MacBook Air

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...

In class, we showed the equation for electroosmotic mobility and electrophoretic mobility. Using these two equations, derive the equation for Vtotal and tm. Recall the equation for Vep = MeE and Veo = MeoE.
