the figure shows a horizontal human arm lifting a dumbbell. the forearm is in equilibrium under the action of the weight w of the dumbbell, the tension t in the tendon connected to the biceps muscle, and the force e exerted on the forearm by the upper arm at the elbow joints. we neglect the weight of the forearm itself. (for clarity, the point a where the tendon is attached is drawn farther from the elbow than its actual position.) given the weight w and the angle between the tension force and the horizontal, find t and the two components of ē (three unknown scalar quantities in all)
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.
