slope?
The pull strength is expected to increase by 2.744 units for every unit
increase in wire length, when die height is zero units.
The pull strength is expected to increase by 1 unit for every 2.744
units increase in wire length, when die height is zero units.
The pull strength is expected to increase by 1 unit for every 2.744
units increase in wire length, when die height is one unit.
The pull strength is expected to increase by 2.744 units for every unit
increase in wire length, when die height is kept constant.
The pull strength is expected to increase by 2.744 units for every unit
increase in wire length, when die height is one unit.
The pull strength is expected to increase by 1 unit for every 2.744
units increase in wire length, when die height is kept constant.
