The angle between A and horizontal is 60, angle between D and horizontal is 70,angle between BC and horizontal is 30. Mass of P is 2kg.
Find: (a) Tension in AB, BC and CD
(b) Mass of Q.
I have been trying to solve this question by using the following 3 equations but I still cant get the answer: ABsin60 + BCsin30 = 2g
CDsin70 + BCsin30 = m(Q)g
ABcos60 = CDcos70 + BCcos30
Can anyone help me to solve this question? Thanks.
