Question 3 CITY_GUILDS_MODEL_QUESTIONS_VOL1 • 2024 • ENGINEERING • practical

A single fixed pulley is used to lift a load. The load weight is 150 N. The effort force applied to the rope is measured as 45 N. During the lift the effort end of the rope moves 0.80 m while the load rises 0.20 m. All measurements are taken with a calibrated spring‑scale and a metre rule. Using the data provided, answer the following:

Question Parts

( a )

Calculate the ideal mechanical advantage of the pulley system.

( b )

Determine the actual mechanical advantage from the measured distances and compute the overall efficiency of the system (expressed as a percentage to two decimal places). State briefly why the actual MA differs from the ideal MA.

( c )

Identify two possible sources of error in the experiment and suggest one practical way to minimise each error.
