3-14. Consider the one-link planar robot shown in Figure P3.14. If l = 5 cm, sketch the position of the tip of the robot and determine the (x,y) coordinates of position P for (a) θ = 45° (b) θ = 0° (c) θ = -135° (d) θ = -90°
3-15. Repeat problem P3-14 if l = 10 in and (a) θ = 150° (b) θ = 270° (c) θ = 420° (d) θ = 90°
