Tandem bicycle stem that is clamped around the captain's seatpost. The stoker handlebars are typically bullhorns or drop bars with "dummy levers" instead of brake levers for gripping. Because of the extra weight and stresses, tandem wheels may use a higher spoke count, sturdier rims, higher pressure tires, a stronger freewheel, dishless spoke configuration, or asymmetric wheels. Tandems wear out rear wheels faster than front wheels; therefore, they may use non-symmetrical wheel setups, such as more spokes or a sturdier rim on the rear wheel. The dish of a wheel measures the amount of asymmetry between the rim and the hub flanges.
Rigs of Rods of Rods was initially created as an off-road truck simulator, but has developed into a versatile physics sandbox game. Prior to version 0.28, the game was limited to typical land vehicles with wheels, but plane and boat engines have been added since. All engines allow for a wide range of customization, leaving virtually no boundaries. Vehicles are built using vertices connected by beams. Vertices (or "nodes") are influenced by the stress on the beams that connect them. If a beam is too stressed, it will deform, thus altering the associated nodes position which ultimately alters the appearance and handling of
