I thought I had this stuff figured out, but my answer is wrong. Any tips? Thanks 1. The problem statement, all variables and given/known data A sign hangs precariously from your prof's office door. Calculate the magnitude of the tension in string 1 if theta-1 = 26.10degrees, theta-2 = 54.87degrees, and the mass of the sign is 6.50 kg. http://img89.imageshack.us/img89/1089/prob05signly6.th.gif [Broken]http://g.imageshack.us/thpix.php [Broken] 2. Relevant equations [tex]\sum[/tex]Fx = T1x - T2x = 0 [tex]\sum[/tex]Fy = T1y + T2y - Fg = 0 Fg = mg 3. The attempt at a solution X components: T1x = T1 Cos 26.1 T2x = T2 Cos 54.87 Y components: T1y = T1 Sin 26.1 T2y = T2 Sin 54.87 [tex]\sum[/tex]Fx = T1Cos 26.1 - T2Cos 54.87 = 0 So... T1Cos 26.1 = T2Cos 54.87 T1 = T2(Cos 54.87/Cos 26.1) and [tex]\sum[/tex]F = T1Sin 26.1 + T2 Sin 54.87 = (6.5 kg)(9.8 m/s2) Then I tried plugging that T1 in there... T2(Cos 54.87/Cos 26.1)Sin 26.1 + T2Sin 54.87 = 24.7 N T2(0.6408)Sin 26.1 + T2Sin 54.87 = 24.7 N T2(0.2819) + T2(0.8178) = 24.7 N T2(0.2819 + 0.8178) = 24.7 N T2 = 22.5 N I can't attempt any more solutions as the assignment was due 20 minutes ago (it's online)... but I did poorly on my midterm yesterday so I really need to get a better understand of the material before it's too late... any advice would be greatly appreciated!
