Two Beads on a String, N Beads on a String
Lecture Section 1.3, Lecture Section 1.4.1
When we write down Newton's second law equations describing the transverse motion of masses coupled by strings (see Equations 1.16 and 1.26 in Section 1.3 and Equation 1.34 in Section 1.4 of the lectures), how do we determine the direction (sign) of each term?
