In the design of a control mechanism, the vertical slotted guide is moving with a constant velocity x˙ = 15 in. /sec during the interval of motion from x = −8 in. to x = +8 in. For the instant when x = 6 in., calculate the n- and t-components of acceleration of the pin P, which is confined to move in the parabolic slot. From these results, determine the radius of curvature ρ of the path at this position. Verify your result by computing ρ from the expression cited in Appendix C /10.
