- Why can’t you put your heels firmly against a wall and then bend over without falling?If 25 kg is the maximum mass m that a person can hold in a hand when the arm is positioned with a 105° angle at the elbow as shown in the figure below, what is the maximum force, FM, that the biceps muscle exerts on the forearm? Assume the forearm and hand have a total mass of 2.0 kg with a CG that is 15 cm from the elbow, and that the biceps muscle attaches 5.0 cm from the elbow. (please include given and explain step by step) E 105° max 5.0 cm 15 cm 25 kg (2.0 kg)g -35 cmRelationship between slip and torque?
- Even when the head is held erect, as shown in the figure, its center of mass is not directly over the principal point of support (the atlanto-occipital joint, Point A). The muscles at the back of the neck should, therefore, exert a force to keep the head erect. That is why your head falls forward when you fall asleep in the class. If the head weighs 43 N, calculate the force exerted by the muscles FM using the information in the figure. Assume that x1 = 5.1 cm, x2 = 2.7 cm, and |Fw = 43 N. N What is the force Fj exerted by the pivot on the head? F; = N Question Credit: OpenStax College PhysicsI'm trying to solve this question but I am getting confused because I am trying to figure out how to do it the simplest way and what is the actual answer because I am getting different answers from other people and can you also explain it to me step by step the easiest way.Explain how dumbbell curls (flexing the elbow while holding dumbbells) with (A) the forearms supinated and (B) the forearms pronated signifncalty alter the demands placed on the elbow flexors.

- Hold your upper arm vertical and your lower arm horizontal with your hand palm-down on a table, as shown. If you now push down on the table, you’ll feel that your triceps muscle has contracted and is trying to pivot your lower arm about the elbow joint. If a person with the arm dimensions shown pushes down hard with a 90 N force (about 20 lb), what force must the triceps muscle provide? You can ignore the mass of the arm and hand in your calculation.What purpose is served by a long and flexible pole carried by wire-walkers?What defines the center of gravity of a rigid body, and how is it related to the center of mass?
- In using the spring scale to find the equilibrant, why does one hold it horizontally on its body and not on its (topmost) handle?Rotational motion is considered in analyzing static equilibrium problems. Whenever torque equation is used, the axis of rotation to be considered in an object for which these are measured: must be located at the edge of the object. must be located at the object's center of gravity. can be located anywhere. must be located at a pivot.Does a bridge anchored resting on two pillars have any torque? None, it isn't moving Yes, but it will soon break because of the torque None, Bridges can't have torque Yes, but it is at equilibrium
