Title: GMA Forces question help!
Post by: M_BONG on September 30, 2013, 09:55:32 pm

Can anyone help me with this question please:

Q10: GMA Ch20.1 Q10

"A string is connected to two points at A and D in a horizontal line and weights of 12kg and W kg are attached at points B and C. If AB, BC, CD make angles of 40, 20 and 50 degrees respectively with the horizontal, calculate the tensions in the string and the weight W"

I don't do Physics and this is probably the hardest chapter for me ATM. Can someone help me with drawing the diagram? I am struggling with that part already so no way can I finish the question.

Hey M_Bong,
I believe this is what the diagram should be, please excuse my lack of artistic ability.
Blue line is the string, green lines are the triangles we construct to show the angle from the horizontal.
