The patellar tendon attaches to the tibia at the tibial tuberosity at a perpendicular distance of 4.91 cm from the center of the knee joint. During an isometric contraction, the lower leg is held at an angle of 35° of knee extension with a 400 N weight strapped to the ankle. The weight is 52 cm from the knee joint center. What is the force produced by the quadriceps to hold this position? Ignore the weight of the leg.
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.
