What import shape gave the Roman bridges and apueducts their strength?

The Roman bridges and aqueducts were primarily strengthened by the use of the arch shape. This architectural design allowed for the even distribution of weight and the ability to span large distances without the need for excessive material. The semicircular arch not only provided structural integrity but also enabled the construction of higher and more durable structures, making it a hallmark of Roman engineering. Additionally, the use of concrete further enhanced the resilience and longevity of these constructions.

What is the effects of a moving load along the arch on the support reaction of two hinged arch?

The effect of a moving load along a two-hinged arch primarily influences the support reactions by altering the internal forces and moments within the arch. As the load moves, the distribution of forces changes, leading to varying reactions at the supports. This dynamic behavior can result in fluctuating vertical and horizontal reactions, which must be accounted for in structural analysis to ensure stability and safety. Overall, the support reactions will vary depending on the load position, impacting deflections and stress distribution in the arch.

I wish to pay for the euro tunnel with my nectar points how many will it take to go from folkstone to calais?

To pay for the Eurotunnel using Nectar points, you'll need to check the specific redemption options available, as the points required can vary based on the service and any promotions. Typically, for standard travel, around 2,500 Nectar points equals £10. You would need to calculate the total fare for your journey and convert that amount into Nectar points accordingly.
