A person holds onto a 50 N dumbbell with their forearm parallel to the ground and their elbow angle at 90 degrees. Please keep your units as Newtons and centimeters. Force Moment arm Ball 50 N 40 cm 20 cm Forearm + hand 15 N A) Draw a free-body diagram (5 points) B) Calculate the torque magnitude about the elbow joint using the following table (10 points). C) What is the anatomical direction of the torque you calculated in B (flexion or extension)? (2 points) D) Another person tries to do the same task as described above; however, they cannot hold onto the ball. You then place it into their hand, and they drop the ball again. What can we say about their muscular strength? You can assume that everything from the table for this question has remained the same (both force and moment arms). For full points, you need to use your answers from B and C to justify your reasoning (5 points).
