You are to assess the biomechanics of a male’s arm using his bicep to hold a 20 kg object in his hand. The upper arm is perpendicular to the ground while the forearm is parallel to the ground. The male’s forearm is 26.5 cm long and weighs 1.42 kg. The man’s hand weighs 0.54 kg and is 19 cm long. The center of masses for the forearm and hand are 43% and 50% of the extremity lengths from the proximal...

A person with their upper arm vertical and their forearm horizontal holds a 4.5-kg iron cannon ball as shown in the figure below. Assume the mass of the forearm and hand is 1.5 kg, with a center of mass 15 cm from the elbow. The center of the cannonball is 32 cm from the elbow, and the force of the biceps is applied 5.0 cm from the elbow. What force is exerted by the bicep? Elbow contact point 4.5 kg...

Interactive Exercises 9.04: Center of Mass (Robotic Arm) Robotic arms have been used on factory assembly lines for many years, but new research into the direct control of robotic arms by humans is creating an opportunity for disabled individuals to regain some degree of lost mobility-see Fig. 9.4.1. In this application, you are to analyse a simple model of the upper part of a robotic arm to find the location of its center of mass. The model is shown in...

The total mass of the arm shown in (Figure 1) is 3.5 kg . The
location of the center of mass of the arm is shown, FM is the force
exerted by the deltoid muscle on the upper arm, and FJ is the
normal force from the shoulder joint on the upper arm.
Part A
Determine the magnitude of the force required from the deltoid
muscle to hold up the outstretched arm in the position shown.
Part B
