Calculate the mobility of the linkage Fork Joint A O B E C0

Calculate the mobility of the linkage

Fork Joint A O) /B E C0 ( O Spring Slider 7777 77 777777 F Go 0 C ((o

Mobility of the linkage, m = 3(n-1) - 2j1 - j2

n is the no. of links = 10 ( Fixed Walls, C0 support and Fork Joint support.and rest are mentioned below)

j1 = no. of links having single degree of freedom = 5 (C0C, CB, DE, EF, slider)

j2 = no. of links having double degree of freedom = 2 (Spring, AD)

So, m = 3(10-1) - 2×5 - 2 = 15
