Pulley-Supporting Frame

Track rope tension, support force, and pulley mechanical advantage without double-counting forces.

Rigid-body statics

explore task

Count rope segments supporting the moving block, then transfer the resulting pulley force to the frame.

\mathbf{F}_{B,1}=-\mathbf{F}_{B,2}

A member pinned at only two ends with no intermediate load is treated as a two-force member. Otherwise, retain all pin components and moments required by equilibrium.

Diagrams are schematic equilibrium models. Member lines do not show elastic deformation, buckling, connection flexibility, or second-order effects.

Model scope and verification

Use the displayed units and idealizations, then verify the governing balance or compatibility equation before interpreting the result.
