These are normally set up over a …

Determining Mechanical Advantage using the T-Method with an added Pulley on the Load

Calculating mechanical advantage: the T-system The subtle but significant difference to this system… a pulley on the load and the main line terminated at head of the tripod. We have a 6:1 mechanical advantage in the pulley system. 1. Assume continuous strands of rope have the same amount of tension. If we start at the …

Mechanical Advantage: Calculation of MA with the T-Method in a Simple System

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 …
