Question 1 CITY_GUILDS_MODEL_QUESTIONS_VOL1 • 2023 • ENGINEERING • practical

A student uses a two‑component force sensor to measure the horizontal (Fx) and vertical (Fy) components of a force acting on a test rig. Five independent readings are obtained as shown in the table. | Trial | Fx (N) | Fy (N) | |-------|--------|--------| | 1 | 30 | 40 | | 2 | 28 | 42 | | 3 | 32 | 38 | | 4 | 31 | 39 | | 5 | 29 | 41 | Using these data, determine the overall magnitude of the force and the reliability of the measurement.

Question Parts

( a )

Calculate the resultant force magnitude for each trial.

( b )

Find the mean resultant force from the five trials.

( c )

Determine the standard deviation of the resultant forces and express the percent uncertainty of the mean resultant (percent uncertainty = (SD / mean) × 100%).
