The biceps tendon connects 4.00cm from the elbow and pulls straight up, while the barbell is held 35.0cm from the elbow. Assume the weight of the forearm is negligible, and that each arm supports half the weight of the barbell. A) What is the tension in the tendon connecting the bicep to the forearm while held stationary in the position shown? B) What is the force (magnitude and direction) of the upp arm pushing on the forearm at the
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.
In the strict curl weightlifting event, a standing athlete lifts a barbell using only their lower arms, hinging at the elbow. The record weight is 900N. The biceps tendon connects 4.00cm from the elbow and pulls straight up, while the barbell is held 35.0cm from the elbow. Assume the weight of the forearm is negligible, and that each arm supports half the weight of the barbell. A) What is the tension in the tendon connecting the bicep to the forearm while held stationary in the position shown? B) What is the force (magnitude and direction) of the upp arm pushing on the forearm at the elbow joint?
