Place fixed and moving pulleys. Route a rope through your build and test the force needed to lift the load.
For you as a guide: Discuss your prediction, run the test and compare one change.
Your rope supports the load with 0.95 vertically effective strands. Compare force and rope travel.
Place pulleys in the scene. In rope mode, tap the anchor, pulleys and pull handle in order. Moving pulleys belong to the same load block. Arrow keys move the selection.

A fixed pulley mainly changes pull direction. A moving pulley is supported by several rope segments. Less force requires more rope travel.
The load and all installed moving pulleys belong to one block. With angled ropes only the vertical component of tension supports the load.
Compare a fixed and a moving pulley with the same load and pulling force. First watch the lift, then compare rope travel.

One massless, inextensible rope; small ideal guides without contact geometry. Each pulley is visited once. All moving pulleys share one load block. Pulling force is constant during a test. Rope travel is computed from the change in geometric rope length; pulley radii and wrap arcs are neglected. Efficiency represents aggregate losses. Pulley mass and small motion damping are included. Lifting stops before the upper block.
A simulation for exploring together. It does not design real electrical installations, lifting equipment or machinery.
