Sheet (3)Position Analysis1-The attached figure shows the mechanisms for the problems each of which refers tothe part of the figure having the same letter. Reference all calculated angles to theglobalXYaxes.a.The angle between theXandxaxes is 25. Find the angular displacement oflink 4 when 2 rotates clockwise from the position shown (+37) to horizontal(0). How does the transmission angle vary and what its minimum betweenthose two positions?b.Find and plot the angular position of links 3 and 4 and the transmission angleas a function of the angle of link 2 as it rotates through one revolution.c.Find and plot the displacement of piston 4 and the angular displacement oflink 3 as a function of the angular displacement of crank 2.d.Find and plot the angular displacement of link 6 versus the angle of inputlink2 as it is rotated from the position shown (+30
