Screw-drive vehicles have one feature in particular that stands out to give them their strange appearance. If you're looking for a way to traverse large areas of snow, muck or mud, a screw-drive vehicle might be exactly what you need.
The unusual manner of propulsion seen on screw-drive vehicles is related to a principle called:
Stairway to Babylon
One 1920s screw-drive vehicle that went into production was based on this popular tractor of the era:
The Soviet-era ZiL-29061 was developed to do what?
Haul nuclear missiles into remote regions where they would not be detected by NATO spy satellites.
Rescue cosmonauts after they landed in unreachable areas following their space missions.
Transport enemies of the state to gulags in the hinterlands.
Screw-drive vehicles are known for the ease with which they drill right over or through difficult terrain. One surface over which they're NOT very handy is this.
Thick, deep mud
Dry, solid ground
In some cases, the oversized cylinders on screw-drive vehicles have been used as what?
Military forces experimented with screw-drive vehicles to use in the snow because tanks had a tendency to do this.
Prevent soldiers inside from viewing the lovely landscape
To be too loud
Sink so deep in the snow that their treads spun out
The Fordson Snow Devil possessed tremendous hauling power. In a promotional video it can be seen pulling what large tonnage of logs?
Half a ton
20 tons (18,144 kilograms)
100 tons (90,718 kilograms)
Snowbird 6 did NOT use its spiral cylinders to do this:
Grab hold of ice to clamber out of the water
Propel itself through snow, slush and water
Defend against predators such as killer whales and polar bears
In their elements of mucky terrain, screw-drive vehicles can reach speeds up to:
5 miles per hour (8 kilometers per hour)
10 miles per hour (16 kilometers per hour)
60 miles per hour (96.6 kilometers per hour)
To move sideways, a screw-drive vehicle must turn its screws in this manner.
In opposite directions from one another
At half speed
In the same direction as one another
A screw-drive vehicle moves forward by doing this.
Turning both its screws in opposite directions
Turning both its screws with the brakes applied
Turning both screws in the same direction
Jacob Morath, awarded a patent for a screw-drive ploughing machine in 1899, was an immigrant to the United States from which country?
The Weasel, a small, maneuverable troop transport developed for use in snowy terrain for the U.S. military in World War Two, used which of the following to traverse the snow in its final design?
Tank-like tracked treads
What was the name of the 2002 expedition that used a hybrid screw-drive and tracked vehicle to cross between the United States and Russia?
To Russia, With Love
The Armstead Snow Devil had a devil of a time when sent to Alaska to perform work. Why?
Amorous male caribou often mistook it for a female of their own species
Operators' hands became too numb from the cold to drive the vehicle
The dry, powdery snow did not provide enough traction for the Snow Devil
Johannes Raedel developed a screw-drive vehicle for possible use by the military of which country?
The United States
The Soviet Union
Under the Soviet Union, this company built a fearsome-looking screw-propelled vehicle, of which you can find videos circulating on the Internet today.
This industry uses screw-propelled vehicles to this day, to break up and dry vast deposits of goop after conducting certain operations.
Certain food processing
Which of these hazards did the Snowbird 6 team NOT face when driving their tracked and screw-propelled vehicle from the United States to Russia?
Ice floes that could tear the vehicle apart
Numbingly cold temperatures
Run-ins with migrating giant squid
Regular tires are inferior on snow or mud compared to screw-drives. But why?
Most tires don't offer enough friction to effectively push back against very muddy or snowy surfaces
Rubber tires break down faster in cold or moist environments
