Description The Fischertechnik Machine that will be analyzed in this report is a scissor lift. Overall, the scissor lift is 6 inches wide, 4 inches deep and 10 inches high. The scissor lift contains a platform at the top to hold objects and that platform sits on a base that is 3 inches high. There is a wheel at the right end of the machine that is used to control their height of the platform. When the wheel is turned clockwise the platform raises; when the wheel is turned counterclockwise, the platform lowers.

Visual Analysis Side: This is a side view of the scissor lift. Overall there is no balance between the top and bottom of the lift and there is no balance between the right and left of the machine. The base and the platform have difference in visual weight. The base of the lift shows balance between the yellow vertical supports and the black columns. The base takes the shape of a rectangle and is made of rectangular components. The top portion of the lift uses the rectangular shapes to make diagonal lines that correspond with the motion of the lift. There is contrast between the arms of the lift as one is yellow and the other is black. There are red components scattered randomly throughout the machine. There is emphasis provided by the large red platform that sits unevenly at the top of the lift. Front: This view shows the scissor lift from one end. There is symmetry and balance between the right and left of the machine as the same colors are used on each side. There is more weight at the top of the machine, as the bottom is made of simple rectangular supports while the top has the platform and the arm of that provides the lifting.

This is the back view of the scissor lift. This contains a heavy emphasis on the black It also shows symmetry and balance between right and left sides of the machine. One this side there is more weight at the bottom of this machine because of the circular shape of wheel.

Product Analysis 1. The purpose of this product is to lift and lower an object on the platform 2. Sketch

3. The product operates by turning a wheel at the end of the machine. The wheel causes a worm gear to turn. Wedged into the worm gear is the end of a support arm. Turning the worm gear causes the support arm to rotate. This rotation caused the raising of the platform 4. Input and Out puts
