2 cards from this section. Quick, good the night before a test.
What shape does a cable take under uniform distributed loads?
Think about the curve formed under the load.
Where does the maximum tension occur in a cable?
Consider the points where the cable is anchored.
What type of load causes a cable to take on a parabolic shape?
Recall the definition of a distributed load.
The maximum tension in a parabolic cable occurs:
Consider where the cable experiences the greatest force.
A cable is 20m long and is subjected to a uniform load of 400 N/m. Calculate and graph the shape of the cable under this load.
Use the equation derived for parabolic shape.
An engineer needs to design a cable system for a 100m long bridge experiencing a distributed load of 1000 N/m. Discuss the implications of the cable's parabolic shape on the structure's stability and design.
Think about the balance between material selection, weight, and design considerations.
