What is the kinematic equations relating the end-effecter position and orientation to the joint displacements. 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 atthe origin O. Namely, the distance between point O and point A is 1, a constant, and theangle 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 andjoint displacements shown in the figure, answer the following questions.yLink 3BJoint 3Link 2Link 1Joint 2AᎾLink 0Joint 1Link 0xex

Block String Rod Disk Mech 3. As shown above, a uniform disk is mounted to an axle and is free to rotate without friction. A thin uniform rod is rigidly attached to the disk so that it will rotate with the disk. A block is attached to the end of the rod. Properties of the disk, rod, and block are as follows. Disk: Зт, radius R, moment of inertia about center ID = mR² mass = %3D Rod: m, length = 2R, moment of inertia about one end IR mR? mass = Block: mass = 2m The system is held in equilibrium with the rod at an angle 0, to the vertical, as shown above, by a horizontal string of negligible mass with one end attached to the disk and the other to a wall.

Required information The figure shows a weapon called a battering ram (modern large battering rams are typically mounted on armored vehicles). The ram has a weight W,= 2500 lb, center of mass at E, and radius of gyration kf= 6.5 ft. The distance between points A and B and between points Cand D is 6 ft. Consider h= 4.5 ft and d= 3 ft. The connections at points A, B, C, and D are pin connections, and assume that the cart does not move while the ram swings. Assume that AB and CD are inextensible cords with negligible mass. In addition, assume that, at the instant shown, e = 10° and the ram is swinging forward with v E = 4.5 ft/s. -d-l ram E At this instant, determine the acceleration of E, as well as the tensions in the cords AB and CD.
