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.

Textbook Question

Chapter 11, Problem 85GP

BIO Triceps To determine the force a person’s triceps muscle can exert, a doctor uses the procedure shown in Figure 11-64, where the patient pushes down with the palm of his hand on a force meter. Given that the weight of the lower arm is M_g = 15.6 N, and that the force meter reads F = 89.0 N, what is the force f_T exerted vertically upward by the triceps?

8₁ 02 9. The diagram of the leg shows the femur (1) and tibia (2). The quadriceps muscle (3) applies a force to the lower leg via a tendon (4) that is embedded with the kneecap (5). If the force applied by the muscle to the tendon is F 570 N, what is the force of the femur on the kneecap, if the leg is in equilibrium? A simplified model of the leg is shown next to the diagram. The leg bones are represented by two beams attached by a pin. The tendon is modelled by a rope and the kneecap acts like a pulley. The tendon above the kneecap makes an angle 8, = 38° with respect to the vertical, and the portion of the tendon below the kneecap makes an angle of 6₂ = 10° with respect to the vertical. Enter the x component, followed by the y component. Answer 1 of 2: Answer 2 of 2: Submit All Answers

The two structural members, one of which is in tension and the other in compression, exert the indicated forces on joint O. Determine the magnitude of the resultant R of the two forces and the angle which R makes with the positive x-axis. The angle is measured counterclockwise from the positive x-axis. 5.4 KN 2.5 KN Answers: R = i 0 = i 31° /1 14 sata, 201 57³ KN O

If, when bent over, the hands are at a horizontal distance of 76.0 cm from the sacrum and the back muscles are at a horizontal distance of 44.0 cm from the sacrum and act at a 12.0° angle above the horizontal, what is the component of the force exerted by the back muscle that compresses the spine?
