2 cards from this section. Quick, good the night before a test.
What is the shape of a cable under a uniform load?
Think about how a sagging rope looks when it's attached at both ends.
What does the horizontal force (H) represent in cable mechanics?
Remember, H doesn't change in our calculations.
What is the shape of a cable under uniform loading?
Think about how a sagging rope dips.
True or False: The horizontal tension (H) in a cable can vary depending on the load.
Remember that this is true as long as we are not accounting for extra external forces.
A cable is 100 meters long and designed to carry a load of 1000 N uniformly. Calculate the sag if the horizontal force in the cable is 500 N.
Plug in the values carefully into the formula.
Describe how real-world factors like wind or temperature can affect the calculations of tension and sag in cable structures.
Think about how these external conditions would influence the stability of the cable.
