The Copper Connection Podcast – Season 2, Episode 6

In this episode, we break down the mechanical science principles that every Building Services Engineering apprentice needs to master. From the invisible forces that keep structures standing to the simple machines that give us mechanical advantage, we’ll uncover the physics that underpins lifts, pumps, fans, ducting, and everyday building systems.

Why do engineers use long spanners to undo tight bolts? How does a pulley make lifting heavy loads easier? What happens to air velocity when duct sizes change? By answering questions like these, we’ll show how mechanical science bridges theory and practice in BSE.

Through clear explanations and practical site examples — from pipework supports to lift motor sizing — this episode reveals how forces, motion, work, and power shape the built environment around us.

Define energy and its forms (kinetic, potential) and explain how energy conversion underpins systems like pumps, motors, and solar panels.

Describe forces and loads (gravity, self-weight, imposed and live loads) and understand their effects on building components.

Apply Newton’s Second Law (F = ma) to real-world examples such as lift cars, pumps, and moving machinery.

Explain work, power, and efficiency and relate them to plant sizing, motor ratings, and energy management in buildings.

Understand moments, equilibrium, and centres of gravity and their application to beams, supports, rooftop units, and hoisting heavy plant.

Identify different types of simple machines (levers, pulleys, screws, Archimedes’ screw) and explain how mechanical advantage is gained in practice.

Explore velocity in BSE systems, from airflow in ducts to water velocity in pipes, and understand why control of speed, flow, and direction is critical to safe, efficient operation.

Appreciate the direct link between mechanical science principles and safety, efficiency, and regulatory compliance in building services.
