Problem: Given the question: I have a test where I am given the following article, what is an answer for the question: What can cause problems when drilling with high torque? ? The two main requirements of an anti-torque system are that it should prevent rotation of the sonde, and it should allow easy movement of the drill up and down the borehole. Attempts have been made to design drills with counter-rotating components so that overall torque is minimized, but these have had limited success. Five kinds of anti-torque systems have been devised for use with cable-suspended EM drills, though not all are in current use, and some drills have used a combination of more than one design. The first drill to require an anti-torque system was used at Camp Century by CRREL in 1966; the drill incorporated a set of hinged friction blades that swung out from the sonde when the drill motor was started. These were found to have very weak friction against the borehole wall, and were ineffective; the drill had to be controlled carefully to prevent twisting the cable. No other drills have attempted to use this approach.For the next deployment of the drill leaf springs were installed, and this has proved to be a more durable design. These are mounted vertically, with a curve outwards so that they are easily compressed by the borehole wall, and can slide up and down with the movement of the drill. They pass easily through any areas of irregularity in the borehole, but the edges of the springs cut into the borehole wall and prevent rotation. Leaf springs are very simple mechanically, with the additional benefit of being easy to adjust by changing the spacing between the end points. They can be placed anywhere on the drill that does not rotate, so they do not add length to the sonde. The shape is usually a fourth-order parabola, since this has been determined to provide the most even loading against the borehole wall. Leaf springs have been found to be so effective that they can prevent rotation even in heavy drills running at full power.Skate antitorque systems have blades attached to vertical bars which are pushed against the borehole wall; the blades dig into the wall and provide the...

Problem: Given the question: I have a test where I am given the following article, what is an answer for the question: What is the full name of the person who has been involved with other acts such as Chino Moreno's Team Sleep and Vanessa and the O's? ? In 2001 the compilation Rotten Apples was released. The double-disc version of the album, released as a limited edition, included a collection of B-sides and rarities called Judas O. The Greatest Hits Video Collection DVD was also released at the same time. This was a compilation of all of the Pumpkins promo videos from Gish to Machina along with unreleased material. Vieuphoria was released on DVD in 2002, as was the soundtrack album Earphoria, previously released solely to radio stations in 1994. Billy Corgan and Jimmy Chamberlin reunited in 2001 as members of Corgan's next project, the short-lived supergroup Zwan. The group's only album, Mary Star of the Sea, was released in 2003. After cancelling a few festival appearances, Corgan announced the demise of the band in 2003. During 2001 Corgan also toured as part of New Order and provided vocals on their comeback album Get Ready. In October 2004 Corgan released his first book, Blinking with Fists, a collection of poetry. In June 2005, he released a solo album, TheFutureEmbrace, which he described as "(picking) up the thread of the as-of-yet-unfinished work of the Smashing Pumpkins". Despite this, it was greeted with generally mixed reviews and lackluster sales. Only one single, "Walking Shade", was released in support of the album. In addition to drumming with Zwan, Jimmy Chamberlin also formed an alternative rock/jazz fusion project band called Jimmy Chamberlin Complex. The group released an album in 2005 titled Life Begins Again. Corgan provided guest vocals on the track "Lokicat". James Iha served as a guitarist in A Perfect Circle, appearing on their Thirteenth Step club tour and 2004 album, eMOTIVe. He has also been involved with other acts such as Chino Moreno's Team Sleep and Vanessa and the O's. He continues to work with Scratchie Records, his own record label, as well. D'arcy Wretzky has, aside from one radio interview in 2009, not made any public statements or appearances nor given any interviews since leaving the band in 1999. On January 25, 2000,...

Problem: Given the question: I have a test where I am given the following article, what is an answer for the question: What team played permanently at the temporary stadium of the team who usually played at Old Trafford? ? Trafford Park was largely turned over to the production of war materiel during the Second World War, such as the Avro Manchester and Avro Lancaster heavy bombers, and the Rolls-Royce Merlin engines used to power the Spitfire, Hurricane, Mosquito and the Lancaster. The engines were made by Ford, under licence. The 17,316 workers employed in Ford's purpose-built factory had produced 34,000 engines by the war's end. The facility was designed in two separate sections to minimise the impact of bomb damage on production. The wood-working factory of F. Hills & Sons built more than 800 Percival Proctor aircraft for the RAF between 1940 and 1945, which were flight tested at the nearby Barton Aerodrome. Other companies produced gun bearings, steel tracks for Churchill tanks, munitions, Bailey bridges, and much else. ICI built and operated the first facility in the UK able to produce penicillin in quantity.As an important industrial area, the park suffered from extensive bombing, particularly during the Manchester Blitz of December 1940. On the night of 23 December 1940, the Metropolitan-Vickers aircraft factory in Mosley Road was badly damaged, with the loss of the first 13 MV-built Avro Manchester bombers in final assembly. The new Ford factory producing aircraft engines was bombed only a few days after its opening in May 1941. Trafford Hall was severely damaged by bombing, and was demolished shortly after the war ended.In the December 1940 air raids, stray bombs aiming for Trafford Park landed on Old Trafford football stadium, the nearby home of Manchester United, but this air raid only resulted in minor damage and matches were soon being played at the stadium again. On 11 March 1941, however, stray bombs aimed at Trafford Park fell onto Old Trafford for a second time, causing serious damage to the stadium. It was comprehensively rebuilt after the war and re-opened in 1949, until which time Manchester United played their home games at Maine Road, the stadium of Manchester City in Moss Side.At the outbreak of war in...
