So here in the p part of the question we are given a four bar mechanism of the length of the couple is given that is equals to 12 to the length of the outbreak is given that is equals to 5 and length of the fixed term is given that is equals to 13.
00:12
We are given the input angle which can rotate at an angle of 360 degree.
00:16
We have to determine the largest value of the length of the input.
00:19
So here we have to find out the largest value of the length of the input from here.
00:24
So here we can say that the length of the input from here is given as we are considering we are having the value of the number of the binary links from here that is equals to n that is equals to 1 2 3 4 5 6 and 7 and 8 and the number of the lower charts is given as j that is equals to 10 that is a b c d e f g h i and j.
00:52
So binary at ratio here we are using the kirchhoff's -kuber's equation where the value of the length is what we need to find out that is 3 of n minus 1 minus 2 of j that is multiplied by the 3 8 minus 1 minus 2 that is multiplied by 10.
01:06
So the value of length from here is equals to 1 m.
01:08
This is answer to the first part.
01:09
Now we are considering about the part b of the question where we have to obtain the mobility.
01:16
So mobility as we have discussed we are having the number of binary links that are 8 and that of the lower charts that are equals to 10.
01:23
So we are using the kutchback -grublev equation.
01:30
We are using the krutchberg -grublev equation according to that equation the value of d of f become equals to 3 of n minus 1 which is multiplied by the minus of 2 of j that is equals to 3 of 8 minus 1 minus 2 that is multiplied by 10.
01:43
So solving the term we get the value of d of f that is equals to 1.
01:46
Hence the answer to the first part.
01:48
Now for the second part we can say that this mechanism is not over constraint.
01:57
This is not over constraint because it has only independent input.
02:08
It has only independent input...
