This table will be updated frequently. Please check regularly for most recent updates and assignments.

5/18 M 12.2
12:4,  5 and 6
12.7
Straight line motion
curved motion, (x,y,z), projectiles
normal tangential coordinates

(beginning page 15) 12: 6,  12,  16,  27 
(beginning page 43) 12: 67, 74, 85, 90
(beginning page 56) 12: 101, 107, 111
 In section 12.7 we will only do plane motion (no 3-d).  Also in section 12.7 we will avoid problems where radius of curvature must be determined by calculus (as in book example 12.14).
5/20 W 12.9 
12.10
12.8
Dependent motion
Relative Motion
Polar Coordinates
(beg. p. 88) 12: 173, 179, 182
(beg. p. 88 ) 12: 199, 202
(beg..p. 71) 12: 152, 155
 In Section 12.9 consider only  chords that move in a straight line, although possibly different directions  (e..g.,  Fig. 12-36 and 12-37 are fair game, but example 12.24 is beyond our current scope).
In section 12.8 we again only consider 2-d motion (ignore z stuff at top of page 65).
5/22  F
13.1-13.3
F=ma
(beg. p. 117) 13: 5, 24
Quiz on Chapter 12.
5/25 M no class



5/27 W 13.4
F=ma Rectangular coordinates
(beg. p. 117) 13:  15, 23, 33, 35 , 42, 45
5/29 F 13.5
F=ma normal-tangential system

(beg. p. 132) 13: 66, 73, 76


6/1 M 13.6
F=ma cylindrical  coordinates (beg. p. 144) 13: 87, 92 Quiz on Chapter 13.
6/3 W 14.1-14.2,

Work and energy

(beg. p. 179)  14: 2, 12, 16, 23, 36

Note that we will not cover section 14. 4 (even though it is easy).  Also ,  I did not list section 14.3 since I found it to be rather preachy (and it makes simple ideas seem harder than they need to be). The most important idea in section 14.3 is the equation in the middle of page 173, and you will understand this equation if you understand Example14..2 on page 174. Note that all the examples 14.1-14.6 are useful for understanding sections 14.1 and 14.2.
6/5 F 14.5 - 14.6
Conservation of energy
(beg. p. 205) 14: 75, 77, 80, 96

6/8 M 15.1-15.3
Linear impulse and momentum (beg. p. 223) 15: 4, 16, 28
(beg. p. 237) 15: 48, 51, 52

6/10 W 15.4
Impact
(beg. p. 249) 15: 59, 68, 78, 79, 88
Quiz on Chapters 14 and 15.
6/12 F 16.1-16.3
16.5
Rigid body motion basics,
Velocity analysis for plane rigid bodies
(beg. p. 312) 16:18
(beg. p. 335) 16:  56, 58,
In the example problems, I much prefer the vector analysis procedures.
6/15 M 16.5
16.7
Velocity analysis for plane rigid bodies
Intro to Acceleration for plane rigid bodies
(beg. p. 335) 16:  63, 65, 70

In the example problems, I much prefer the vector analysis procedures.
6/17 W 16.7 Acceleration analysis for plane rigid bodies (beg. p. 360) 16: 107, 110, 116, 128
Quiz on Chapter 16
sections 16.1-16.3, 16.5
6/19 F 17.2-17.3
17.4
Translational motion

(beg. p. 409) 17: 26, 30, 32

Ignore Example 17.13 as this is better done by energy methods (however study example 17.10)
6/22 M 17.4-17.5
Rotation about a fixed axis
General plane motion (rods)
(beg. p. 422) 17: 58, 75,  78,
(beg. p. 436) 17: 100, 103
In doing problems of this type, I expect to see  a "force picture= motion picture" diagram.  Note that the book example problems: 17.7, 17. 8, 17. 9, 17.11 (solution I), 17.13, 17.15, and 17.16 draw rather weak "motion pictures"  by showing an axis system rather than a picture of the body.   I strongly encourage you to draw a picture of the body for the motion picture as well.
6/24 W  17.5  General plane motion (rolling) (beg. p. 436) 17: 91, 99, 102 Quiz on Chapter 17
Chapter 17 except for free rolling
6/26 F 18.1-18.4
Work and energy for rigid bodies
(beg. p. 460) 18: 7, 26, 28
In some of the examples in this chapter, they calculate the velocity using the method of instantaneous center taught in Section 16.6.  We did not cover this method due to time constraint and also because the vector method always works.  Note that all velocities and angular velocities  in the examples can be determined by the standard vector method: vB = vA + w x AB.
6/29 M 18.5 Work and energy for rigid bodies, using potential energy to simplify the calculation of work.
(beg. p. 474) 18:52, 54
