Total questions: 10
Worksheet time: 5mins
Why does designing for an 'average' person often fail in product design?
Human bodies rarely change over populations
People vary across dimensions, not all average
Average height predicts all other dimensions
Adjustability increases complexity without benefit
In the bakery image, what specific awkward posture is shown and why is it risky?
Arms abducted with hands above shoulder height, increasing shoulder load
Neck flexed with extended wrists, increasing carpal tunnel pressure
Back fully flexed while twisting, increasing lumbar disc stress
Knees locked in hyperextension, increasing ligament strain
Which description best matches the persistent stage of a musculoskeletal injury?
Symptoms appear quickly and last longer; sleep may be disturbed
Symptoms occur only during heavy work; resolve immediately with rest
No interference with tasks; strength and comfort rapidly return
Symptoms are constant at rest; daily activities are severely disrupted
Which control type is considered most effective for preventing ergonomic injuries in the workplace?
Behavioral reminders given during meetings
PPE that protects workers as last resort
Administrative controls that change procedures
Engineering controls that change the workplace
When lifting a box from the floor, which action best maintains spinal stability?
Relax the core while lifting
Twist at the waist to pivot
Keep the natural lower back curve
Hold the load away from torso
What is the primary goal of applying ergonomic design principles?
Eliminate all physical effort entirely
Reduce training time for staff
Achieve productive harmony at work
Maximize aesthetic appeal only
What does understanding the 'blueprint of the human body' enable in design?
Matching tools to human capabilities
Eliminating need for training entirely
Prioritizing style over function
Reducing all movement to zero
A bakery switches to adjustable shelves to reduce reaching. Which principle is applied?
Continuous ergonomic improvement
Random task rotation schedule
Aesthetic uniformity in storage
One-time hazard acceptance
In planning a new workstation, what is the best first step?
Identify task demands and body limits
Buy the most advanced chair available
Copy a popular online setup exactly
Assume one size fits all users
Which metric best evaluates productive harmony after changes?
User comfort and task efficiency
Total floor area repainted
Color matching of equipment
Number of posters on safety
