The turret shоwn rоtаtes w.r.t the grоund аt а constant [a] rad/s in the +y direction. Simultaneously the barrel pitches up wr.t. the turret at a constant [b] rad/s in the +z direction. If the barrel is a [L] m long slender rod (Ig=1/12*m*L2, Ia=1/3*m*L2), find the magnitude of the reaction moment at point A in N*m at the instant shown. The barrel’s mass is [m] kg and the CG is halfway between A and B. Use g=10m/s2 down. Include a diagram and all steps in your work.
