How to find the DImensions of all the parts of the device

  1. May 25, 2007 #1
    1. The problem statement, all variables and given/known data
    As picture attached .We need to find the dimensions of all the parts that are Pin(A),Jaw(B and C), NUt (D) , Handle (E) .The jaw B is fixed and C is free to move towards B.There is a force T=1779.261 N on Jaw C.Secondly there is a human force involved in turning the handle (E) which is maximum of 100 N and can not exceed it.We need to find the dimensions for all the components discussed , especially the diameter of the threaded nut ,the verticle length of the Handle and the DIameter of the Pin being used.
    U can see the mechanism of car jack .its exactly the same jsut the difference is that tehre are two jaws in place of traingle in car jack.

    2. Relevant equations

    3. The attempt at a solution
    Well i think if we can possibly relate the work done is covering the distance with the force applied over the handle then we can caluculate the diemnsions of Handle and for the diameter of Nut if we can find its realtion with inertia .
