Work, Power and Energy Transfer Questions and Answers

Work, mightiness and Energy Transfer Questions and AnswersAmy HarrisTask 1Packing cases of mass 25kg argon to be fomented onto a ramp by use of ahydraulic ram as shown above. The coefficients of static and high-power frictionbetween the quoin and surface are 0.7 and 0.4 respectively. Assuming uniformacceleration at on the whole stages. prefigurea) The maximum lastingness required in the ram to push the crate onto the slopewith an acceleration of 0.25msb) The speed of the crate as it leaves the exit part of the ramp assumingthis part of the movement takes 1 second.c) The velocity of the crate at the bottom of the rampd) The distance travelled aft(prenominal) leaving the ramp and continuing in a straight delineate (assume a smooth curve at the bottom of the slope).e) The total duration for the entire movement of the crate.Corrections to Task 1Task 2A pile driver turncock of mass 300kg is raised to a height of 3.5m before being released. If there is no rebound aft(prenomina l) impact with a pile of mass 500kg and the pile is driven 0.1m into the build, Calculate a) The initial potential energy of the hammer before release. b) The velocity of the hammer instanter before impact c) The velocity of the hammer and pile immediately after impact d) The deceleration of the pile assuming it is uniforme) The ground resistanceCorrections to Task 2Task 3 let the velocity of the hammer immediately before impact for the caper inclined in Q2 above using DAlemberts Principle and write a report comparing it with the preservation of energy method previously used. How do the dickens methods differ and what were the discrepancies in the results?The DAlemberts Principle faeces in some parts, be very similar to the second equity motion which Newton introduced. He thought that the law could be rewritten so that we can achieve the behavior of an equilibrium. This rule was made by Jean le Rond dAlembert, he was a French mathematician in the 18th century. It is explai ned as reducing a problem in dynamics to a problem in statics (The Editors of Encyclopaedia Britannica, 2016). I found that when referring to the time derivatives of the momenta of the ashes (Wikipedia, June 2016) DAlemberts principle shows this equation F-ma=0 (The Editors of encyclopedia Britannica, 2016). I researched this formula and found that F=ma(classes R., no date) and newtons second law states that F= mg (Kearsley, no date) This means that when no external force is present we may use the formula mg-ma=0. Dalemberts principle is different to the conservation of energy method as dalemberts uses the equilibrium of forces when referring to a dynamic system and the conservation of energy method states that in a closed dynamic system the energy total equals zero. They may differ sometimes as they are dealing with different values to come out with the answer, to a fault aspects such as human error when rounding comes into play as a small rounding error can sometimes push the a nswer. The conservation of energy method is used more than the that of DAlemberts, perhaps because it is not often that a system is balanced completely which is when DAlemberts is used.The answer I got is the same as I do with the other method, this shows that this method can be used to prove the answer found in assign 2.
