Exam 3: Basic Biomechanical Factors and Concepts

In order for rotation to occur in objects with a fixed axis an eccentric force must be applied in line with the center of rotation of the object.

Which of the following could be done to reduce the amount of force needed to move a lever?

Which of the following is not an example of forces that act individually or in combination to provide mechanical loading that may result in excessive tissue deformation?

Which of the following statements is true about velocity?

Slight variations in the location of a force and a resistance have no effect in determining the mechanical advantage (MA) and effective force of a muscle.

Which of the following terms is defined as the rate of change in velocity?

Which of the following levers would be most effective to use to move a specific object if your only objective was a slight movement of the object?

Short force arms and long resistance arms require great muscular strength to produce movement.

Muscles are the main internal source of force that produces or changes movement of a body segment or an entire body.

Kinematics is concerned with the description of motion and includes consideration of each of the following except:

Which of the following is a primary purpose of wheels and axles in the musculoskeletal system?

A resistance arm is defined as the distance between an axis and the point of resistance application.
