Final answer:
Stable footing and a low center of gravity are essential when applying a side mounted hand brake. These elements are crucial for maintaining balance and stability in various scenarios, from riding a bicycle to steady camera holding and correct posture.
Step-by-step explanation:
When applying a side mounted hand brake, an employee must have stable footing and a low center of gravity. For stability, the center of gravity should be aligned with the base of support, whether one is on a bicycle or in a standing position. This concept is similar to riding a bicycle where the cyclist leans at the correct angle to ensure the force from the ground goes through the center of gravity, providing stability during a turn. The same principle applies to holding a camera steady or maintaining good posture, with a stable base and low center of gravity helping to prevent falls or strain.
