Flashcards in Test 2, Ch. 3-4 Deck (9):
1

What is true about tension with a pulley

the cable on the pulley is subjected to a constant tension throughout its length

2

Moment

the measure of the tendency of the force to make a rigid body rotate about a point of fixed axis

3

Magnitude of cross product

ABsin(theta)

4

Principle of transmissibility

a force can be applied anywhere along its line of action and still create the same moment

5

Couple force

two forces having the same magnitude but opposite direction and separated by a distance d.

6

Where does r point for a couple moment

from -F to F

7

If you move F to point o what must you add to the system?

a moment equal to the moment generated by F about o before it was moved

8

Concurrent force system

the lines of action of all the forces intersect at a common point

9

coplanar system

the lines of action of all the forces are in the same plane
