Additional Information for Educators and Administrators

This set can be used in the classes addressing the following topics: Physics, Shop, Construction, Engineering, Bridge Building, Architecture.

Specific concepts addressed with this set: This kit concentrates on the areas of Mechanics known as Dynamics and Statics.

Mechanics—the effects and forces which affect rigid and moving bodies.

Dynamics—describe the change of the movement variables. Whenever machines or gears units are set in motion, they are dynamic.

Electric Motors and the concepts of Revolutions Per Minute (RPM), and Gear Units. Gears—overview of the various types--Worm Gear Pairings, Toothed Gearing and Crank Gears—build basic models using each of these different gears to learn the principles behind them and their specific functions.

Vehicle Drives—build three different vehicles using each of the above gear types to learn how these affect transmission ratio and torque. Build two additional models--a vehicle incorporating Toothed Gearing with Chains, and a Vehicle with Fifth Wheel Steering to learn the principles behind these important modifications.

Build and study models of a Compound Gear Unit, a Planetary Gear and a Bevel Gear Unit. Experiment with the differences in speed and direction when shifting from one gear to another in each. Learn where such gears are commonly found. Build a model of a Kitchen Mixer combining both a Bevel Gear and a Planetary Gear.

Differential Gear—learn how a differential gear is used and why it is important. Build a working model to study it’s function.

Build a working model of a Car Jack and a Scissor Elevating Platform to learn about Mandril Screw Spindles, Joints, and Levers. Perform tasks to help answer questions about each model. Next, build a working model of Lathe using two spindle drives.

Crank-Rocker Gear Unit--Build a model of a Windshield Wiper using this gear, and study how it transforms a rotational movement into an oscillating (back and forth) movement.

Build a Four-Bar Chain Unit consisting of four joints. Observe how the components interact and move.

Build a model of a Hacksaw Machine to understand a coupler mechanism.

Build a working Beam and Scales to learn about the principles of levers of equal length.

Build a model of Scales with a Sliding Weight to experiment with the use of torques.

Physics Golden Rule--Build a working Lifting Tackle with 2, 3, and 4 Rope Pulleys. Experiment with lifting a weight with each variation, and record your observations. This will help students to understand Physics “Golden Rule”—“Work cannot be saved. Whatever is saved on force, must be added in time and distance.” Statics—the study of conditions under which the force acting on a body are in balance. This is the basis for all calculations and designs of constructions such as bridges or houses.

Dead weight and traffic load. Statical Triangles--Build a Table model to learn about statical triangles, which are statically stable in all three aspects. Experiment with different variations of bracing the table and record your observations.

Build a Double Ladder to make further observations about bracing and stability.

Bridge Design Fundamentals--Build a Girder Bridge, a Bridge with Underbeam, and a Bridge with Upperbeam. Experiment with weights on the bridge and learn about the advantages and disadvantages of each design.

Skeletons--Build a High Hunting Stand to learn about skeletons--the spatial composition of individual frameworks.

Finally, students will integrate what they have learned about mechanics, levers and statics from the construction of the previous models to build a working crane model. Students will complete several tasks and record their observations.
