Screenshot 2025-02-13 134728.png In occupational therapy a patient is asked to hold an object with their right hand. The object has a weight of 30 N and is located 0.460 m from the elbow joint. The center of gravity of the forearm is located 0.150 m from the elbow joint and the weight of the arm is approximately 18 N. The bicep muscle pulls up on the arm 0.040 m from the joint as the patient holds the ball level. a. What force(s) rotate the arm counterclockwise and which rotate the arm clockwise? b. Calculate the torque due to the object’s weight. c. Calculate the torque due to the arm’s weight. d. What is the torque due to the biceps muscle? e. Calculate the Force due to the biceps muscle.

A spring with an unstretched length of 40.0 inches is hung from the ceiling. A 10.0 lb weight is then hung from the bottom of the spring and stretches it downward by 4.00 inches. The weight is then pulled a further 6.00 inches downward and released from rest. Calculate: a) the spring constant of the spring b) the frequency of the resulting oscillations c) the maximum velocity of the weight as it bounces up and down

A guitar string is 26.8 inches long and weighs 0.198 oz.  It is tightened to a tension of 43.0 lbs. Find the frequency of the second harmonic the string will produce when plucked.  Reminder: There are 16.0 oz in a pound.
