Problem 1E

A crayon manufacturer is comparing the effects of two kinds of yellow dye on the brittleness of crayons. Dye B is more expensive than dye A, but it is thought that it might produce a stronger crayon. Four crayons are tested with each kind of dye, and the impact strength (in joules) is measured for each. The results are as follows:

a. Can you conclude that the mean strength of crayons made with dye B is greater than that of crayons made with dye A?

b. Can you conclude that the mean strength of crayons made with dye B exceeds that of crayons made with dye A by more than 1 J?

Step 1 of 3

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 attache
