The accurate installation of a simple gear holds significant importance as an incorrect installation can lead to machine malfunctions. Beyond affecting the engine's performance, such errors can compromise the safety of machine users. Hiring individuals with a solid understanding of mechanical concepts is vital for success in mechanical and manufacturing roles.

The Mechanical Reasoning test evaluates candidates' grasp of physics and mechanics principles. This screening tool assesses candidates in three key areas of mechanical concepts: force and movement, velocity, and pulleys, gears, and wheels. Through questions addressing real-life problems and events, the test gauges candidates' ability to perceive the relationship between physical forces and mechanical elements in practical situations.

High-performing candidates in this test demonstrate a robust understanding of mechanical and physical principles. They possess a level of mechanical aptitude conducive to proficiency in relatively straightforward mechanical roles and functions. The test ensures that these candidates possess all the necessary mechanical comprehension skills for handling tasks involving moderately complex equipment.
