A baby swing has 4 DOF: One for the angular orientation of the swing with respect to the frame, and 3 for the location and orientation of the frame with respect to a 2-D frame.

A folding baby walker has 4 DOF: One for the degree to which it is unfolded, and 3 for the location and orientation of the walker with respect to a 2-D frame. A fancy corkscrew has 2 DOF: The screw can be rotated and the arms rotate to translate the screw. A windshield wiper mechanism has 1 DOF: The position of the wiper blades is defined by a single input. A dump-truck dump mechanism has 1 DOF: The angle of the dump body is determined by the length of the hydraulic cylinder that links it to the body of the truck. A trash truck dumpster mechanism has 2 DOF: These are generally a rotation and a translation.

A pickup tailgate mechanism has 1 DOF: n. An automobile jack has 4 DOF: One is the height of the jack and the other 3 are the position and orientation o the jack with respect to a 2-D frame. A collapsible auto radio antenna has as many DOF as there are sections, less one. DESIGN OF MACHINERY - 5th Ed. SOLUTION MANUAL 2-2-1 PROBLEM 2-2 Statement: How many DOF do you have in your wrist and hand combined? Solution: See Mathcad file P0202. Holding the palm of the hand level and facing toward the floor, the hand can be rotated about an axis through the wrist that is parallel to the floor (and perpendicular to the forearm axis) and one perpendicular to the floor (2 DOF).

The wrist can rotate about the forearm axis (1 DOF). Each finger (and thumb) can rotate up and down and side-to-side about the first joint. Additionally, each finger can rotate about each of the two remaining joints for a total of 4 DOF for each finger (and thumb). Adding all DOF, the total is Wrist 1 Hand 2 Thumb 4 Fingers 4x4 16 TOTAL 23 DESIGN OF MACHINERY - 5th Ed. SOLUTION MANUAL 2-3-1 PROBLEM 2-3 Statement: How many DOF do the following joints have? Your ankle c. Your shoulder d.

Your knuckle Solution: See Mathcad file P0203. 1 DOF: A rotation about an axis parallel to the ground. 3 DOF: Three rotations about mutually perpendicular axes. Your shoulder. 3 DOF: Three rotations about mutually perpendicular axes.

3 DOF: Three rotations about mutually perpendicular axes. E Your knuckle. 2 DOF: Two rotations about mutually perpendicular axes. DESIGN OF MACHINERY - 5th Ed. SOLUTION MANUAL 2-4-1 PROBLEM 2-4 Statement: How many DOF do the following have in their normal environment?

A submerged submarine b. An earth-orbit satellite c. A surface ship d. A motorcycle (road bike) e. A two-button mouse f. A computer joy stick. Solution: See Mathcad file P0204.

A submerged submarine. Using a coordinate frame attached to earth, or an inertial coordinate frame, a submarine has 6 DOF: 3 linear coordinates and 3 angles.

An earth-orbit satellite. If the satellite was just a particle it would have 3 DOF. But, since it probably needs to be oriented with respect to the earth, sun, etc., it has 6 DOF. A surface ship. There is no difference between a submerged submarine and a surface ship, both have 6 DOF. One might argue that, for an earth-centered frame, the depth of the ship with respect to mean sea level is constant, however that is not strictly true.

A ship's position is generally given by two coordinates (longitude and latitude). For a given position, a ship can also have pitch, yaw, and roll angles. Thus, for all practical purposes, a surface ship has 5 DOF. A motorcycle. At an intersection, the motorcycle's position is given by two coordinates.

In addition, it will have some heading angle (turning a corner) and roll angle (if turning). Thus, there are 4 DOF. A two-button mouse. A two-button mouse has 4 DOF. It can move in the x and y directions and each button has 1 DOF. A computer joy stick.

The joy stick has 2 DOF (x and y) and orientation, for a total of 3 DOF. DESIGN OF MACHINERY - 5th Ed. SOLUTION MANUAL 2-5-1 PROBLEM 2-5 Statement: Are the joints in Problem 2-3 force closed or form closed?

Solution: See Mathcad file P0205. They are force closed by ligaments that hold them together. None are geometrically closed. DESIGN OF MACHINERY - 5th Ed. SOLUTION MANUAL 2-6-1 PROBLEM 2-6 Statement: Describe the motion of the following items as pure rotation, pure translation, or complex planar motion. A windmill. 1.
