The mechanism shown in the figure is used to lower and retract the landing gear on small airplane. The wheel assembly (link 4) weighs 100lb, with a centre of gravity as shown. The motor link (link2)is rotating counter clockwise at 3 rad/s and accelerating at 10 rad/s^2. For mass property estimation, the motor crank will weigh approximately 15lb and will be 2 ft long, 1 ft wide, and 0.25 ft thick. The connecting link (link3) is estimated to weigh 20 lb and can be modelled as a 3.5-ft slender rod. Determine all forces acting on the joints of all links and torque required to drive the motor link. Given: a,2 = 11.91 @102°. ag3 = 19.21 @90.6°: , ag4 = 20.32 @73.4° ft/s2 rad rad az = 4.1 s2 С.С.
