Document Summary

Remarks: lab 5 due monday, november 26, 2018. A massless rope is suspended over a smooth (frictionless) pipe. Masses are hung from either end of the rope. A and b : the tension is case b is greater than that case a, the masses accelerate. A and c : the tension is the same -> left side equilibrium. Fnet = 0 = t-mg. t = 9. 8*1 n. T -mg = ma -> t=m(a+g) a=( +)g = (cid:2871) -> t= ((cid:2870)+)g = (cid:2872)(cid:2871) Two blocks, a and b, of equal mass are connected by a rope od negligible mass that hangs vertically from the ceiling as shown. T1 is the tensioning the rope above the block a, and t2 is the tension is the rope between two blocks. T1 mg -t2 = 0 t2 - mg = 0. T1 t2 -t2 = 0 -> t1 = 2t2 -> t1/t2= An object is held in place by friction on an inclined surface.
