City Guilds Model Questions Vol1 2017 Engineering Question 3
Practice practical question 3 from the 2017 City Guilds Model Questions Vol1 Engineering examination. This question covers Coefficient of friction, Newton’s second law, Experimental error analysis .
A smooth wooden board 1.20 m long is placed on a rough horizontal surface. A 2.00 kg wooden block is placed at one end of the board. The block is pulled down the board by a string attached to the block and passing over a frictionless pulley at the opposite end of the board. The string is attached to a hanging mass that provides a constant pulling force. The experiment is to determine the coefficient of kinetic friction (µk) between the board and the surface. The following data are recorded during the experiment: - Mass of the hanging weight (M) = 0.80 kg - Acceleration of the system measured with a stop‑watch over 5 s after release = 0.45 m s⁻² - Length of the board that moves during the measurement = 0.60 m - The board is level (no incline).
