If a task requires too much force, what can be an ergonomic improvement?

Answer and explanation

Correct answer: Reduce force by suitable tool or method

The direct answer is A: reduce the required force with a suitable tool or method. Ergonomics tries to fit the task to the worker, not to force the body beyond safe limits. A handle, lever, wheeled device, adjustable height or improved technique can make the same job require less muscular effort. The reasoning is: excessive force → greater body strain and injury risk; suitable aid → lower force → safer, more sustainable work. Option A is correct. Option B is wrong because increasing force increases fatigue and risk. Option C is wrong because blaming a worker does not improve the task. Option D is wrong because removing breaks prevents recovery and may worsen fatigue. A useful exam cue is to choose the option that reduces unnecessary effort while preserving the work.
