The Efficiency of screw jack formula is defined as the ratio of tan of the helix angle to the tan of the sum of the helix angle and angle of friction and is represented as;
n = tan(α)/(tan(α+Φ)) or;
Efficiency = tan(Helix Angle)/(tan(Helix Angle+Angle of friction)).
So, Answer (B) is the Right Answer.
n = tan(α)/(tan(α+Φ)) or;
Efficiency = tan(Helix Angle)/(tan(Helix Angle+Angle of friction)).
So, Answer (B) is the Right Answer.
