Hi, I have been trying to attempt this problem for quite some time and I would be very gracious if anyone could help me out. A clothes-line is attached to two fixed ends which are 10.0m apart. A pully of mass 40.0 kg hangs freely in the middle of the line. The sag at the centre is .20 m. Find the tension in each half of the clothes line. Marking is as follows (I figure it might give a guidline as of what I need to do) -1 mark for steps 1 and 2 Step 1: Select the object to be studied (This is the pulley) Step 2: Draw a free body diagram (I have no problem doing this although I cannot do it on the computer) Step 3: Choose a set of x and y axes for each of the objects being analyzed and resolve the free body diagram into components that point along these axes *This is where I get into trouble* Step 4: Set up the equations in such a way that the sum of the x components of the forces is zero, and the sum of the y components is also equal to zero. (I know where the x and y components are and such but I am having difficulty making an equation and solving it because there is no angle written or told of and I have no idea how to solve for it otherwise. Step 5: Solve the equations for the unknown quantities you are looking for. (I really have no idea how to do this without knowing the previous 2 steps) I hope someone knows how to do this cause I am really stumped. Anyways could you also explain how to show magnitude and distance with this type of problem? I have looked this up on the internet and I was thinking of renting a grade 12 40S textbook from my local library. By the way this is a grade 12 level physics course. Thank you.
