  • Force Table
    Force Table, Deluxe w/10 sheets

    Here's the classic way to study force and vectors. Our lightweight, accurate device has a performance that exceeds the degree of accuracy needed for most high school or college applications. Our 16" (40 cm) diameter masonite disc balances on our sturdy cast-iron tripod base. The disc has a permanently printed decal with large, easy-to-read numerals. It is graduated in two 360° scales to prevent parallax error. The weight harness snaps into...

  • Roman Arch Set
    Roman Arch Set, Pine.

    Build a working model of the Roman Arch and learn why this structure is so strong. This clever and attractive puzzle is also an intriguing lab in force and geometry. Try building it without the template first - it's not as easy as it looks! Build it on a flat surface and then carefully raise it up. The kit includes: 23 pine blocks in 6 unique shapes; predrilled buttress in 3 sections; hardware; instructions with historical background and...

  • Catenary Arch Set
    Catenary Arch Set.

    Here's a great hands-on lab for physical science, math or even art. Our streamlined set of blocks helps you understand the unique structural strength of an arch of this type. While the mathematical workup is complex, the basic shape needn't be. Kit includes: 13 wood blocks, all about 2" long and 1/2-1" thick; instructions with full-size template.

  • Center of Gravity Paradox
    Center Of Gravity Paradox.

    Things are not always what they seem. Our angular momentum apparatus is weighted at one end. Try to balance the one meter rod with the heavier end down; intuition tells most people this should work. In actuality, the opposite is true - turn the rod over and balance it easily on a mere fingertip. This is a hands-on way to introduce the concepts of the center of gravity, angular acceleration and moment of inertia. Mass is movable. Instructions...

  • Double Cone and Plane
    Double Cone And Plane.

    Defy gravity as our cone appears to roll upward. This visual demonstrator of the center of gravity consists of a wooden frame with diverging rails and a double-ended cone. The cone appears to roll upward; in actuality, it is the center of mass that is moving downward.
