  1. Thanks for the insights! I appreciate the help.
  2. Thank you! While waiting for your answer I discovered another shortcut that is a bit quicker, but only works when the two angles equal 90°. Simply take the sin of each angle and multiply them times mg to get T1 and T2. I think your solution is universal however, even if the angles don't add up to 90°. How often do AP1 questions include this type of question where the angles don't sum up to 90°?
  3. On problem 19(c) of the supplemental questions for AP1 Dynamics I must be doing something wrong with the Trig functions to solve for the tension in each wire, but the problem is not worked out in the answer, it simply says to substitute the appropriate trig functions to solve. Can someone show me the steps for that so I achieve the correct answer? Thanks! AP1 Dynamics 19.pdf
