Transcript of "Coz 2013 2014 block 2"

  1. 1. 2013/2014 - COZ Block 2 - Problem 1 Part A A tractor (which has a mass of 10000 ) is lifted using the cable system shown. Determine the force in cable AC needed to lift the tractor. Express your answer with the appropriate units. ANSWER: = MasteringEngineering: COZ Block 2 http://session.masteringengineering.com/myct/itemView?view=print&a... 1 of 1 29-8-2013 16:20
  2. 2. 2013/2014 - COZ Block 2 - Problem 2 A pin at C and the rod AB support the jib crane, carrying a load. Part A Given that the mass of the load is 2.0 with its center of mass at G, determine the horizontal and vertical components of reaction at the pin C, given that the tension in the link AB is 20.5 . Also determine the distance . Enter your answers numerically (with the correct sign) separated by a comma. ANSWER: Part B Determine the distance . Enter your answer.
