The 4.00- Block In The Figure Is Attached To A Vertical Rod By Means Of Two Strings. When The System Rotates About The Axis Of The Rod, The Strings Are Extended As Shown In The Diagram And The Tension In The Upper String Is 85.0?
The answer here is 36 N. Find the angles in the triangles, the forces in the strings will be proportional but not equal. Find the vertical component of the tension in the upper cable and then take away the gravitational force acting on the top an it will give you the vertical component of the … Read more
