Questions and Answers - Chapter 6

Kenny sent me these questions to answer using the book. The first one was,
Black and blue pegs provide much more friction than the other pegs. The gray and tan pegs have no friction, because they are meant for moving parts. The next question was about parallel linkage. Parallel linkage is when you link two parallel beams with one beam perpendicular, or multiple perpendicular beams at intervals. Tension and compression are both forces. Tension attempts to stretch or lengthen an object, and compression will attempt to shorten or compact an object. Inhertia is the tendency that object have to resist changes when in a state of motion or rest. The added beam on fig 6.10 on page 123 reduces gear slip, and allows the gear to stay on steadily.

The bottom answer might need more information, state which colored pegs (beam linkers) give slip and which give steadiness. (P.S. Send me your Questions)

The answers were kind of bullet point like but you had good answers Kenny's questions
