Ergoweb’s training.
1. Ergonomics is a body of knowledge concerned with:
A. Human abilities
B. Design of tools, machines, systems, tasks, jobs, and environments
C. Fitting the job or task to the person
D. All of the above
2. Which of the following would not be considered a physical work characteristic?
A. A drill
B. A 300-pound supervisor
C. A bushel of potatoes in a produce warehouse
D. A workplace temperature of 40 degrees Fahrenheit
3. The greater the match between worker capabilities and task demands:
A. The greater the chance of worker injury/illness
B. The lower the chance of worker injury/illness
C. Has no impact on chance of worker injury/illness
D. The greater the chance of being exposed to high risk jobs
4. Maximum isometric strength capacity frequently is used to evaluate the risk of performing a job
because:
A. At slow motions, maximum isometric strength is very similar to maximum isotonic strength
B. Maximum strength capability through a range of motion has not been measured by isokinetic
dynamometers
C. At all speeds of motion, maximum isometric strength is the same as maximum isokinetic strength
D. A prediction based on an isometric strength test better approximates actual performance of a
dynamic task than a prediction based on a dynamic strength test
