Question 1.
What type of load do arches primarily transmit?
Show hintHide hint
Think about how cables work since arches are similar.
Question 2.
Name one benefit of using a three-hinged arch.
Show hintHide hint
Consider stability in structures.
3Question 3.
What type of stress do arches primarily deal with?
- Tensile
- Shear
- Compressive
Show hintHide hint
Remember, arches are like inverted cables.
4Question 4.
True or False: A three-hinged arch can experience bending moments at supports.
- True
- False
Show hintHide hint
Think about how hinges affect structural behavior.
Question 5.
Design a two-hinged arch for a bridge, ensuring it can withstand asymmetric loads. Discuss how you'll determine the necessary dimensions and materials.
Show hintHide hint
Start by sketching a moment diagram to visualize forces.
Question 6.
Analyze the potential failure modes of a semi-circular arch under varying live loads. What design principles would you employ to mitigate these risks?
Show hintHide hint
Look at how varying loads can shift the center of gravity.
