10.2.1 Describe linear, rotary, intermittent, oscillating, reciprocating and irregular motion.
Flying pig on Mechanisms and Movement Linear motion is motion that is in a straight line. Rotary motion is motion around a single fixed axis. Intermittent motion is motion that starts and stops at regular intervals. Oscillating motion back and forth motion about a pivot point. Reciprocating motion back and forth motion often used with rotational Irregular motion is motion that does not follow any regular pattern

10.2.2 Explain how linkages can be used to change the direction of motion of components.
Simply, linkages are a set of connected levers that can change the direction of motion, i.e linear into rotational.

10.2.3 Discuss mechanical motion in a range of contexts.
//Consider a hydraulic digger, a bicycle, a car jack and a hand drill.//

10.2.4 Define torque.
Torque //“Rotational force” commonly measured in units of newton metres.//

10.2.5 Discuss the design features of a ratchet and pawl system.
Ratchet and pawl mechanical device that permits motion in one direction only. The ratchet is usually a wheel with slanting teeth. The pawl is a lever tangential to the wheel with one end resting on the teeth. When the wheel rotates one way, the pawl slides over the teeth; when the wheel rotates the other way, the pawl catches in the teeth. "ratchet and pawl."

10.2.6 Describe simple cam shapes and their advantages.

 * Flying pig on cams
 * Technology student on cams
 * It converts rotational or reciprocal motion into oscillating linear motion.
 * Different cams can perform different motions

You can find different type of cam follower mechanism. In general cam follower system cam is rotated and follower move up and down according to cam profile. In my cam follower mechanism, 1. Follower is off set. 2. Force is applied from follower to cam and by using this force cam is rotated. (Major difference) 3. It creates energy.(Difficult to believe) media type="youtube" key="QBFGCyxyQ7Y" height="315" width="420"

10.2.7 Identify cam followers and state their use.
The cam follower traces the surface of the cam transmitting its motion to the required mechanism. //From http://www.flying-pig.co.uk//

10.2.8 Explain the use of a series of cam and follower mechanisms to achieve a set purpose.
//This can be explored in a number of ways: using Lego, paper and pins, or through virtual online models.// in the content of your page here.
