Across
- 6. machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.
- 11. plane/ A flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.
- 12. pair/ A constraint that comprises belts, chains, and such other devices.
- 14. A triangular shaped tool, a compound and portable inclined plane of a wedge is given by the ratio of the length of its slope to its width.
- 15. A device designed to transform input forces and movement into a desired set of output forces and movement.
- 16. first law of motion/ Objects that do not experience any net force will continue to move in a straight line with a constant velocity until they are subjected to a net force.
- 17. linkage/ An assembly of bodies connected to manage forces and movement.
- 19. / A circular movement of an object around a center of rotation.
- 21. machine/A mechanical device that changes the direction or magnitude of a force.
- 22. pair / An ideal joint that constrains contact between a point, line or plane in the moving body to a corresponding point line or plane in the fixed body.
- 24. and axle/ A machine in two parts rotate together in to transfer force from one to the other.
Down
- 1. machine/ A machine formed from a set of simple machines connected in series with the output force of one providing the input force to the next. For example a bench vise consists of a lever in series with a screw, and a simple gear train consists of a number of gears connected in series.
- 2. pair / A constraint that requires a curve or surface in the moving body to maintain contact with a curve or surface in the fixed body.
- 3. motion/ The motion along a straight line, and can therefore be described mathematically using only one spatial dimension.
- 4. law of conservation of mechanical energy/ The mechanical energy of an isolated system remains constant in time, as long as the system is free of friction and other non-conservative forces.
- 5. joint / A two-degrees-of-freedom kinematic pair used in mechanisms.
- 7. joint/ A one-degree-of-freedom kinematic pair used in mechanisms.
- 8. wheel on an axle that is designed to support movement of a cable or belt along its circumference.
- 9. A rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque.
- 10. pair / A connection between two bodies that imposes constraints on their relative movement.
- 13. joint/ A linear sliding movement between two bodies, and is often called a slider, as in the slider-crank linkage.
- 18. A type of bearing that connects two solid objects, typically allowing only a limited angle of rotation between them.
- 20. The tendency of a force to rotate an object about an axis, fulcrum, or pivot.
- 21. / A mechanism that converts rotational motion to linear motion, and a torque to a linear force.
- 23. / A structural element that is capable of withstanding load primarily by resisting bending.
