Scope:

A Cam, Crank and Toggle experiments kit should provide an introduction to cams, rollers and additionally crank motion and toggle.
The kit should help to understand how cams are used, to show how the rotational motion of a cam is transmitted to the linear motion of a follower and how different shapes of cam can be used to achieve varying magnitude and duration of linear motion• Relationship between the angular movement of a pear, heart, round and snail cam and the linear movement of the follower

• Characteristics of a pear, heart, round, and snail cam profile
• Show characteristics of a rotating crank assembly by observing the motion of the system and observe the change in turning moment with crank angular position
• Turning moments and forces during crank motion Engineering Fundamentals Base Unit Base unit should have the following facilities,
• Tool less assembly
• Base Unit backboard with a screen-printed grid reference which all assembly instructions refer to for the location of parts
• Ability to assemble in vertical (landscape and portrait), inclined and horizontal configurations (clear assembly instructions provided for each)
• Measuring scale on backboard
• Improve the student’s dexterity by self-assembly with graphical instructions
• Sturdy common base for all EF experiments to be assembled on
• Screen-printed design should include for measuring scale to help identify correct length thumb screwsetc. Flat-pack for easy storage
• Simple grid reference system to assist with assembly of experiments
