A holiday decoration consists of two shiny glass spheres with masses 0.0240 kg and 0.0360 kg suspended from a uniform rod with mass 0.120 kg and length 1.00 m (?Fig. P11.62?). The rod is suspended from the ceiling by a vertical cord at each end, so that it is horizontal. Calculate the tension in each of the cords A through F.
Solution 66P Step 1: To find the tension in each chord from A to F Step 2: TA= mg = 0.0360 × 9.8 = 0.528N TB= mg = (0.0360 + 0.0240) × 9.8 = 0.5886N T = cos(53.1 ) = T = cos(36.9 ) 1 C C 0 0 TB= T sCn(53.1 ) + T D sin(36.9 ) 2 Solving the equation 1 and 2 we get T = 0.4707N T = 0.3534N C D
