Solved: Find the sequence of pseudorandom numbers

09/06­09/09 In Dynamic muscular contractions we will use Concentric Action and/or Eccentric Action. Concentric action is the shortening of a muscle and going against gravity while Eccentric action is the lengthening of a muscle and going with gravity. In both actions the muscle(s) will be under load. An example ​of this would be doing a bicep curl. When you lift the dumbbell you are using concentric action and when you lower the dumbbell to the initial starting point that is eccentric action. Simple Machines The Musculoskeletal system can be thought of as simple machines which are mechanical levers. We have three different levels each having an axis of rotation which would be the joint, a point at which force is applied which would be where the tendon is attached to the bone, and a point where the load or resistance is applied which would be to the body. We will discuss all three levers but Class 3 is what will be discussed when talking about the body. Class 1 ​: ​Force ­Axis­ Resistance, ​examples of this would be seesaw. It is used to balance movements when the axis is in the middle. Class 2:​ ​Axis­Resistance­Force, ​example of this would be a nutcracker since it used to produce force movements. Class 3 : Axis ­ Force ­ Resistance, ​force is between the axis and resistance. It produces speed and a range of motion. That is why Class 3 is used when talking about the body. A = axis F = force application R = load or resistance FA = force arm or moment arm RA = resistance arm
