Ptolemy's table of chords to the arc angle in degrees as is to 3, or more precisely, the ratio can be made as close as desired to ≈ by making "θ" small enough. Thus, for the arc of °, the chord length is slightly more than the arc angle in degrees. As the arc increases, the ratio of the chord to the arc decreases. When the arc reaches 60°, the chord length is exactly equal to the number of degrees in the arc, i.e. chord 60° = 60. For arcs of more than 60°, the chord is less than the arc, until an arc
Less than truckload shipping different people's shipments on a trailer and since each shipment is technically “less than a truckload” they would consider that to be LTL. There are also freight companies who do not specialize in truck loads, but rather, consolidate larger volume shipments from about 2 to 12 pallets (or about 4000 to 24000 pounds) and consider themselves LTL Carriers. Finally, the most commonly referenced LTL is shipped via “common” carriers who handle freight above what would normally ship via FedEx Ground, or UPS or U.S. Mail parcel services (about 150 pounds) to just under what would usually be considered a Truck
