The winch or grapple holds the trees while the skidder drags them to a landing area. Cable skidders are more labor-intensive than grapple skidders because someone (the operator or a second person) must drag the winch line out to the logs and hook them up manually. Nowadays, cable skidders are less popular than in the past.
The Budweiser Rocket is an American 3-wheeled land vehicle, generally resembling the 1970-era Blue Flame land speed record holding vehicle in appearance, powered by a liquid rocket engine with an extra solid-fuel booster from a Sidewinder missile, [1] that has been claimed as being the first vehicle to have broken the sound barrier on land.
The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible.
This is the first time in history that a land vehicle has exceeded the speed of sound. The new records are as follows: Flying mile 1,227.985 km/h (763.035 mph) Flying kilometre 1,223.657 km/h (760.345 mph) In setting the record, the sound barrier was broken in both the north and south runs. Paris, 11 November 1997.
Through the NACA program, he became the first human to officially break the sound barrier on October 14, 1947, when he flew the experimental Bell X-1 at Mach 1.05 at an altitude of 45,000 ft (13,700 m), for which he won both the Collier and Mackay trophies in 1948. He then went on to break several other speed and altitude records in the ...
During this descent Baumgartner set the record for fastest speed of free fall at 1,357.64 km/h (843.6 mph), [2] [12] [5] making him the first human to break the sound barrier outside a vehicle. [ 38 ] [ 39 ] Baumgartner was in free fall for 4 minutes and 19 seconds, a fall time 17 seconds shorter than the record set during mentor Joseph ...
The Sound Barrier is a 1952 British aviation drama film directed by David Lean. It is a fictional story about attempts by aircraft designers and test pilots to break the sound barrier. It was David Lean's third and final film with his wife Ann Todd but it was his first for Alexander Korda's London Films, following the break-up of Cineguild.
Alvin Orlando Lombard was a blacksmith building logging equipment in Waterville, Maine.He built 83 steam log haulers between 1901 and 1917. [4] These log haulers resembled a saddle-tank steam locomotive with a small platform in front of the boiler where the cowcatcher might be expected.
