Shown below is a construction robot having two revolute joints and one prismatic joint. Notice that the axis of the prismatic joint has an offset of 1 from the first revolute joint at the origin O. Namely, the distance between point O and point A is 1, a constant, and the angle between OA and AB is 90 degrees, a constant as well. Joint 2 is a prismatic joint, whose displacement is given by distance d, a variable. Using the geometric parameters and joint displacements shown in the figure, answer the following questions. y Link 3 B Joint 3 Link 2 Link 1 Joint 2 A Ꮎ Link 0 Joint 1 Link 0 x e x

please i need her solving with using the formulas attached below of pin joint linkage
