Letting RA = 203 mm, RB = 107 mm, RC = 165 mm, and RD = 140 mm, determine the angular acceleration of gears B, C, and D when gear A has an angular acceleration with magnitude |αA| = 47 rad/s2 in the direction shown. Note that gears B and C are mounted on the same shaft and they rotate together as a unit.
