2 cards from this section. Quick, good the night before a test.
Define 'deformation' in terms of cable mechanics.
Think about the change in the cable's length or shape.
What is the horizontal force (H) in a cable system?
Consider what remains constant when there are no horizontal loads.
What is the horizontal force H in a cable system?
Think about the forces involved when there are no horizontal loads.
True or False: The shape of a cable under uniform load is always linear.
Recall the equations and their implications on cable shape.
A cable supports a uniform load of 10 kN/m over a span of 100 meters. Calculate the maximum tension in the cable given a sag of 4 meters.
First, find the horizontal force, then use it to calculate vertical and total tension.
If the sag of the cable is doubled while the same load is applied, what happens to the horizontal force? Discuss its implications.
Reflect on how changes in sag affect redesigning cable systems.
