2 cards from this lesson. Good the night before a test.
Try these first
- 1.
What is a tensile force?
Hint
Think about how cables behave when they hold loads.
- 2.
Define the term ‘sag’ in the context of cables.
Hint
Consider how a hanging rope behaves.
- 3.
What type of force do cables primarily transmit?
- Compressive forces
- Tensile forces
- Bending forces
Hint
Think about the direction in which cables work.
- 4.
True or False: Cables can support compressive forces effectively.
- True
- False
Hint
Consider how cables behave under tension.
- 5.
A cable spans 40 meters between two supports and sags 8 meters. Calculate the sag-to-span ratio and the horizontal thrust.
Hint
Focus first on calculating the ratio correctly.
- 6.
If a uniform load of 500N/m is applied to a cable of length 30m, determine the maximum tension in the cable.
Hint
You might have to calculate r based on the height and span of the cable.
