2 cards from this section. Quick, good the night before a test.
What is a tensile force?
Think about how cables behave when they hold loads.
Define the term ‘sag’ in the context of cables.
Consider how a hanging rope behaves.
What type of force do cables primarily transmit?
Think about the direction in which cables work.
True or False: Cables can support compressive forces effectively.
Consider how cables behave under tension.
A cable spans 40 meters between two supports and sags 8 meters. Calculate the sag-to-span ratio and the horizontal thrust.
Focus first on calculating the ratio correctly.
If a uniform load of 500N/m is applied to a cable of length 30m, determine the maximum tension in the cable.
You might have to calculate r based on the height and span of the cable.
