Testing the UMAB versus wooden boards
To ensure the prescision and quality of each and every UMAB, sophisticated testing was employed during UMAB development.
UMAB designed its own specialized testing equipment that measures board strength and breaking consistency. This equipment was also used to demonstrate how inconsistent and unpredictable wood boards can be.
The physics are simple. A steel weight is dropped from various heights, in a highly controlled process, on the board being tested, to determine the consistency and durability of wood boards versus the UMAB.
The graphs below may be read this way: The left vertical numbers represent the height the weight was dropped from during the testing. The lower horizontal numbers represent the number of times the board was broken for the test.
Each graph shows a straight line where the equivalent wood board should break, on average, based upon its size and strength. However, the bold red lines demonstrate the fluctuations of force needed to break wood boards of equal strength as the UMAB over the course of testing. Each graph also identifies a consistent and reliable test line for each UMAB.
How does wood compare? The results are below.
UMAB White Board vs. 3" wood strip
The three inch wood strip requires weight be dropped on it from heights of one, two, and three feet - giving unreliabe and varied results. In 100 breaks, there are over five different heights that the weight must be dropped from just to break the wood strip. In class, this means each time your students break a three inch wood strip they must use a different amount of force, which could result in injury. The white UMAB board, however, gives a consistent result - the force required to break it does not change through 1000 breaks. The UMAB White Board is perfect for the beginner.
UMAB Yellow Board vs. 5" wood strip
Dropping weight on the five inch wood strip from heights of one to six feet gives unreliabe and varied results. The yellow UMAB board, however, gives a consistent result - the force required to break it does not change even after 1000 breaks. The super tough nylon construction is guaranteed to last, and you no longer have to make last-minute trips to the lumber yard to buy boards.
UMAB Orange Board vs. 7" wood strip
Dropping weight on the seven inch wood strip from heights of one to seven feet shows that even a larger strip is not consistent. Each break requires a different amount of force, depending on the strength and grain of the wood. The orange UMAB board, however, gives a consistent result - the force required to break it does not change even after 1000 breaks. The UMAB has weight and flexibility like wood, but is totally reliable and consistent. This helps your students focus on control.
UMAB Green Board vs. 1 wood board
Dropping weight on a one inch wood board (nine inches) from heights of one to eight feet gives unreliabe and varied results. The green UMAB board, however, gives a consistent result - once the board is broken, the breaks are very consistent. Your students will be assured that every time they break a board they can use the same amount of force. Plus, there are no sharp edges or splinters to worry about.
UMAB Blue, Brown and Black Boards vs. 1 x 1/4", 1 x 3/4" and 2 x 1/4" Wood Boards
Dropping weight on the 1 x 1/4", 1 x 3/4" and 2 x 1/4" wood boards from heights of one to eight feet gives unreliabe and varied results. The blue, brown, and black UMAB boards, however, give consistent results - the force required to break them does not change even after 1000 breaks. All UMAB Boards are stackable for power breaking and are available with padding on the back side for the comfort of the individual holding the board.
