Hello again, I'm stuck on a new problem. Again, I thought I had the correct equation but apparently not as my answer is not correct. Here's the problem: A steel I-beam has a weight of 9.10 N and is being lifted at a constant velocity. What is the tension in each cable attached to its ends? Here is what the picture looks like: http://www.webassign.net/CJ/4-50.gif This is the equation I came up with to solve for this problem but apparently it isn't the correct one. F = (2mg)cos70.0 degrees But like I said, when solving for the above equation my answer is not correct. Any help or direction given would be greatly appreciated.
