r = 1 − 0 . 5 cos ( 2 π t) m θ = 0 . 5 − 0 . 2 sin ( 2 π t) rad . Determine the radial and transverse components of the force exerted on A by the robot’s jaws at t = 2 s. What forces are being exerted on the part? There is some type of radial motion, plus a changing angle θ . We should choose polar. F r F θ ma θ ma r e r e θ The radial force is due to friction of the grips, the transverse force is due to the normal force of the grips. r r a m F = = a m F a a ) ( sin 2 r r m mg F r - = - ) 2 ( cos r r m mg F + = - What next?
