Unformatted text preview: Friction F=uN (impending moion) Tipping/Slipping Check (slip) take moment about opposite side and must fall into range Check (tip) F<Fmax(=uN) Belt Friction 1) Belt is on the verge of slipping F=uN 2) T2 is in the direction of motion T2>T1 T2=T1e^uB (T2 is always in direction of motion, B/contact angle is in radians) **Centroids- equations...
