PHY354H1 Lecture Notes - Ope, Sinj, Statics
Document Summary
Phy254 lecture 2: text readings: morin: 2. 1-2. 2, 3. 1-3. 2. Start going through compwiki website: in this section of the course, we review some of the techniques in me- chanics from rst year, and introduce some new ideas. The approach is really problem based since the theory isn"t so new: in most of the course, we"ll deal with everyday forces: Contact forces: tension, normal force, friction normal force. Setting up f = ma problems: statics: statics is the study of mechanical systems at rest. Suppose you hold the rope with tension t0. There will be a couple of math tricks we use because we are dealing with a small segment. I"ll point them out when we get to them x-balance: y-balance: N t ( + d ) sin(d /2) t ( ) sin(d /2) = 0. T ( + d ) cos(d /2) t ( ) cos(d /2) fs = 0.
