Determine and sketch the dead loads acting along beams AD, DEF, and JKL at the second floor

A 300 ft long steel cable is loaded in tension until the average unit strain is 0.004. d Determine the total elongation under this load.

An engineer is designing a cable system to support a 250 Ib traffic camera and light over the right lanes of a divided highway. She wants to ensure public safety is maintained and needs to find the baseline loads in the two cables (before wind or ice loads are added). Points A and C are at the same elevation. Draw a clear and complete FBD and then find the tensions in the two cables. Make sure you use appropriate notation and units. Show formulas before solving. -80 ft- 20 ft 10 ft 30
