1. The problem statement, all variables and given/known data Door weighs 20kg, and is held open by force P at doorknob opposing 15kg weight attached at C and wrapped around pulley. Theta is 90 degrees, so door is on x axis. Find torques on hinges A & B 2. Relevant equations P is 118.8N in -k direction, which agrees with answer in book. I am getting answers for torques at A & B that don't agree with the book 3. The attempt at a solution Here are summations of torques at B: (1.75j + 1.2i)(1.2i – 1.2k)(147N) T along top (from C to E) (1.75j + 1.2k)(-147j) T from E to 15kg weight (.65j + 1.05i)(-118.8k) P; force on doorknob (.75j + .6i)(-196j) Weight of door (1.5j)(Axi + Ayj + Azk) Forces at hinge A This set of forces yields the following values: -308.7k -308.7i + 211.7j 176.4i -77.2i – 127.7j -117.6k -1.5Axk + 1.5Azi Am I correct so far? Thank you....any help is appreciated.
