Force dial

Force dial: located on the reference instrument. Compare its shape and position with the apparatus used in your practical.

Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.

THE FIRST VIVA QUESTION

What is its use?

Measures grip force for practical assessment and standardised functional testing.

Tap a number to locate its part. Zoom, drag or use full screen to inspect the reference. Models and graduations can differ; check the actual apparatus used in your laboratory.

01 / IDENTIFICATION

How to recognise it.

  1. Two grip surfaces or handles
  2. Force-sensing mechanism
  3. Analogue gauge or digital readout
Tell the difference.

It measures force rather than the electrical activity recorded by EMG or the repeated displacement recorded by an ergograph.

02 / NUMBERED PARTS

Point them out.

Choose a part to bring its numbered marker into view.

03 / WORKING PRINCIPLE

The science behind the reading.

A mechanical or electronic transducer converts applied force into a calibrated reading.

04 / VIVA PRACTICE

Think first. Then reveal.

Explain your answer aloud before opening it.

01What does it measure?
SUGGESTED ANSWER

Grip force under the specified posture, handle setting and test procedure.

02Why standardise position?
SUGGESTED ANSWER

Joint angles and body support affect the force that can be produced.

03Are kilograms on a dial always a mass measurement?
SUGGESTED ANSWER

Many devices use kilogram-force conventions; confirm the instrument’s stated units.

04Why compare repeated attempts?
SUGGESTED ANSWER

They help assess consistency, while allowing for effort, learning and fatigue.
