Force Board With Scales.
This low-cost alternative to the Force Table has an identical method of operation. It is ideal for graphing the composition of forces and the direction and magnitude of vectors. To use, link three spring scales together by a center harness and measure their corresponding angles and distances. Slide paper under the harness to mark the center, trace the position of the arms, and record each reading at the line. Includes: tempered masonite disc...

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, 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.
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.

Truss, Simple Form.
Demonstrate and quantify the effect of force on a mechanical derrick or truss. This basic model provides an interesting introduction to simple bridge building by exploring compressions, tensions and force and equilibrium. Our kit includes: a half-meter knife edge with hooks on both ends; V-shaped clamp; instructions. Ring stand, weights, & spring scale sold separately.

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...
