The 160mm long link AB is shown in figure 1.1 below. The mass of
the link is 2kg. Its CG is at the midpoint (80 mm away from A). Its
mass moment of inertia about its CG is 450kg mm2. An
external force F of 65N at 0 degrees is applied at point B. The
link angle, (Θ) = 20 degrees. Angular velocity of link
omega(rad/sec) = 45. Angular acceleration of link, alpha
(rad/s2) =16. Acceleration of CG,
aCG (mm/s2) = 25200 at angle 185
degrees.
Calculate:
a) Force F12 at pin joint A.
b) Driving torque T needed to maintain motion
