Blocks & Tackle
This interactive simulator explores Blocks & Tackle in Classical Mechanics. n supporting strands, same rope tension T, ideal MA = n, F = T. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Classical Mechanics.

How it works
A block and tackle redirects force with an ideal mechanical advantage equal to the number of rope strands that support the load (and attached movable block), in the limit of massless rope and frictionless pulleys. Tension has the same magnitude along the continuous rope, so the pull on the free end is F = T while static equilibrium gives nT = mg. You gain force but pay in distance: raising the load by Δh requires pulling roughly nΔh of rope through the system.
