Homework Equations
Free body diagram of big box, maybe some trig for finding cables b or c
The Attempt at a Solution
1.
I know that the big box has a Force:weight pointing down of 150 N, and normally, if it was resting on a flat surface it would have normal force pointing up 150N. But because it is suspended by cable A from small box 72N, I'm not sure how to approach finding the tension in cable A. Would it be okay to think the tension in cable A is 150 N + 72 N?
2.
I am thinking I could draw a resultant? and that its magnitude would be 72 N, given by the box hanging from it. and from there do Opp/hyp or Sin (60).
