Your skills to mentally animate a static diagram in a Bennett test are highly related to your spatial visualization ability. You are required to read the question, analyze the diagram and visualize movements of different components of the mechanical object offered in an item. However, there is a limitation to your mental simulation ability. You can’t animate all components of a mechanical diagram simultaneously.
How to handle such limitations in a Bennett Mechanical test?
Simply decompose the system into its components and visualize movements of each component individually. When motion of a component is related to many other components or a mechanical interaction between different components is happening in different planes, the visualization becomes a tricky job. You can score well in a Bennett mechanical test by understanding different mechanical systems.
When a Bennett mechanical test offers a problem of many interactive gears, it becomes difficult to analyze in which direction the last gear shall move. You shall find all gears fixed in their center.
You should animate each gear while keeping movement of a single adjacent gear in mind. This way you can develop a piecemeal strategy to analyze motion of only one gear at a time. In most of such gear problems, you may discover that every other gear will turn into the same direction. In gear related problems, the verbal strategies can also help you to solve the problem. The movement would either be clockwise or anticlockwise in such Bennett mechanical test items.
When you are offered multiple gears and attached belt problems in a Bennett mechanical test, you can solve it by following piecemeal strategy. You will observe that motion of each component can be inferred that of a single component that touches it. However, you can’t go to verbal strategy because frame of reference keeps changing with Axel movement. In other words you can’t represent the movement of the pulley as clockwise or anticlockwise.
The pulley problems in a Bennett mechanical test offer a static diagram of pulley systems. You are required to decide which pulley requires more force to lift the given weight. Some pulley items may differ from others for one or more attributes to see how you combine information from such differences. The variation may take place in relevant and irrelevant attributes. Your responses shall be analyzed by keeping all these variations.
The wheel problems in a Bennett test may require you to visualize movement of a bigger wheel in comparison to the movement of the smaller wheel. You will find several components constraining each other in many ways. In such complicated situations you need to visualize movement of the whole system at once. Your spatial visualization shall be tested at higher degree.
Generally, the Bennett mechanical test does not allow you to make notes upon the static diagrams of mechanics. However, the conditions may change with the change of testing situations. The testers may permit you to make notes on the booklet of the Bennett test besides making selection of choices on the answer sheet. You need to use such permission very wisely. Also keep in mind that your notes shall be analyzed when the psychologists shall analyze your answers to the items in a Bennett test.
