0
Why are guy-wires typically installed radially at equal angles around a structure?
To evenly distribute tension and balance lateral forces for structural stability
To make the structure look symmetrical and aesthetically pleasing
To increase the weight of the structure so it resists wind better

Buttress
Medieval architects defied gravity by mastering the art of buttresses
3 days ago
0
How did the introduction of buttresses change architectural design in ancient buildings?
They allowed walls to be thinner and taller by counteracting lateral forces from roofs.
They were primarily decorative elements with no structural purpose.
They replaced the need for any roof support structures entirely.

Lateral Thrust
Medieval architects turned sideways forces into soaring cathedrals with flying buttresses
5 days ago
0
Why are flying buttresses essential in buildings with vaulted ceilings?
They primarily support the weight of the roof vertically without affecting lateral forces.
They are purely decorative elements with no structural function.
They transfer lateral thrust from walls to external supports, preventing collapse.

Expansion Joint
Structures silently flex and shift daily thanks to hidden expansion joints
6 days ago
0
Why are expansion joints critical in long-span bridges?
They provide extra support to carry heavier loads on the bridge.
They prevent the bridge from moving at all to keep it rigid.
They allow the bridge materials to expand and contract safely with temperature changes.

Corbel Arch
Ancient builders used corbel arches to span spaces without the curved elegance of true arches
8 days ago
0
What is a key structural limitation of corbel arches compared to true arches?
They exert more lateral thrust on supporting walls, requiring thicker supports.
They can span much larger distances without additional support.
They distribute weight evenly through a smooth curved shape.

Guyed Tower
Tensioned cables enable towers to reach dizzying heights with minimal material
10 days ago
0
Why do guyed towers rely on guy lines instead of being self-supporting?
Because guy lines are cheaper than building a strong mast
Because guy lines are only decorative and do not affect stability
Because the mast has compressive strength but lacks shear strength to resist lateral forces alone

Scissor Arch
Intersecting arches in scissor design revolutionized medieval cathedral roofs
10 days ago
0
What is the primary structural advantage of a scissor arch in roof construction?
It uses a single arch to support the roof, eliminating the need for any additional framework.
It balances outward thrust forces by intersecting arches, reducing the need for heavy supports.
It relies solely on vertical columns without distributing lateral forces.

Bridge Span
How the length between supports transforms bridge design and engineering challenges
12 days ago
0
How does the span length influence the choice of bridge design?
Longer spans require stronger materials and specialized designs like suspension bridges, while shorter spans can use simpler beam bridges.
Span length only affects the aesthetic design of the bridge, not its structural requirements.
The span length is irrelevant because all bridges use the same construction methods regardless of distance between supports.
