The following figure represents a bicep curl maneuver where the center of mass (CoM) of a 23 kg dumbbell is 0.29 m from the elbow joint (pivot). The mass of the arm is 5 kg and acts 0.17 m from the elbow joint, and the biceps tendon acts at a distance of 0.01 m from the elbow joint. What is the required magnitude of the resultant joint reaction force (JRF) at the elbow in newtons (N) for the scenario described above in a) where static equilibrium is achieved.
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
