Load pins are designed into sheave applications for measuring line tension. Sheaves are designed with either a variable or constant wrap angle. For the variable wrap angle case, two strain gage bridges are installed perpendicularly (Px and Py). For the constant wrap angle case, one strain gage bridge is installed along the primary (sensing) axis of force (P).
