T Method Applied To Mechanical Advantage Systems Using Rope Grabs

By Lance Piatt / Pulley Systems, Pulleys & Mechanical Advantage

T Method Applied To Mechanical Advantage Systems Using Rope Grabs. Calculating mechanical advantage: the T-system 1. Assume continuous strands of rope have the same amount of tension. If we start at the point where effort is applied and assume that we apply one unit of tension (1T) then we can assume that the tension along …

Actual Mechanical Advantage – Rope Rescue Rigging Systems

By Lance Piatt / Blog, Mainline Systems and Operations, Mechanical Advantage

The T-method of analysis allows us to account for the friction in the pulleys and calculate a more accurate mechanical advantage. The efficiency of each pulley is calculated by measuring the difference between its theoretical output force, from our original system analysis, and its actual output force, determined experimentally. The efficiencies are then multiplied together …
