Tension and compression forces on bridges

Web7 Mar 2024 · Stone is very strong in compression (it handles being “squashed” very well) but is incredibly weak in tension (one half of the slab of stone is being “squashed” while the other half is being “stretched”). Since a slab bridge operates in tension, the stone must be very thick and the span very small for the bridge to be sturdy under heavy loads. WebThere are five terms used to describe what type of force can act on a material: tension - a pulling force; compression - a pushing force; bending - forces at an angle to the material;
