A normal pickaxe handle is made of ash or hickory wood and is about three feet long and weighs about 2.5 pounds. British Army pickaxe handles must, by regulation, be exactly three feet long, for use in measuring in the field. New variant
Four-wheel drive all four wheels a third or 'center' differential can be used to distribute power between the front and rear axles. The described system handles extremely well, as it is able to accommodate various forces of movement and distribute power evenly and smoothly, making slippage unlikely. Once it does slip, however, recovery is difficult. If the left front wheel of a 4WD vehicle slips on an icy patch of road, for instance, the slipping wheel will spin faster than the other wheels due to the lower traction at that wheel. Since a differential applies equal torque to each half-shaft, power is
