Syllabus for our class

THERE WILL BE FOUR TESTS DURING THE SEMESTER- ONE AFTER EVERY TWO CHAPTERS - PLUS A FINAL EXAM! HINT ON TEST: On problem #3, Px is zero. That means that P only has Y and Z components, and you can find them using the angle alpha. Assignments: 1. 3g/m3 =slug/f3 2. 3N = lb 3. 3f/s = m/s 4. 3.0 slugs= kg Do problem 2.3 in textbook.
