To begin with lets solve for the dynamic case where the robot arm is moving We know from physics that in polar coordinates the radial Fr and transverse Ftheta forces can be found using the mass of the ...

Question:

The robot arm is elevating and extending simultaneously. At a given instant, θ = 30°, θ˙ = 40 deg /s, θ¨ = 120 deg /s², l = 0.5 m, l˙ = 0.4 m /s, and l¨ = −0.3 m /s². Compute the radial and transverse forces Fr and F_θ that the arm must exert on the gripped part P, which has a mass of 1.2 kg. Compare with the case of static equilibrium in the same position.
