Picture is attached. The above figure shows a uniform iron beam of mass 254 kg and length L = 3 m. The cable holding the beam in place can take a tension of 1300 N before it breaks. (You may ignore the small mass of the cable in this calculation.) ====== a)What minimum length of the cable? b) Assume the cable is made of steel and has a diameter of 1". How much will it stretch before it breaks? ============ Okay. I am stuck on part a so far. I know that this is a static equilibrium, therefore, the summation of all the forces in x and y direction equal zero. Also, the summation of torques must also equal zero. But I'm not sure how to write out the equations. Can someone give me a lending hand?
