In the context of the foreign exchange market, traders liquidate their positions in various currencies to take up positions in safe-haven currencies, such as the US dollar. Sometimes, the choice of a safe haven currency is more of a choice based on prevailing sentiments rather than one of economic statistics.
Typical commercial US dump trucks are double-axle dually setups carrying about 10 cubic yards of material, which is about 10 short tons for typical materials like gravel or soil. A big, heavy-duty triple-axle model might reach 15 tons. A single-axle model based on a passenger truck might only hold 3 tons. A side-dump semi trailer might hold 30 tons.
depends on the size of the dump truck. The size of the dump box (example if it can hold 10 cubic yards) and the legal loading limit for the roads / area and number of axles the truck has will determine the load it can carry. But let's say it can hold 10 cubic yards for this example. Gravel weighs approx 1.35 tons per cubic yard.
