Max’s Wheel with (SEIKO Socket) vs. T-Handle Wrench (Tooyful): No Winners, No Losers

This paper compares two approaches to applying torque: Max’s Wheel with a SEIKO socket and a Tooyful T-Handle Wrench to remove ONE the pin from the pinblock. The analysis considers their technical specifications, moments of force, and the potential impact of vibrational forces.
1. Technical Specifications
Max’s Wheel (SEIKO Socket):
•   Wheel Diameter: 250 mm (0.25 m)
•   Radius: 125 mm (0.125 m)
•   Stand Height: 150 mm (0.15 m)
•   Applied Force: F≈98.1,N (10 kg)
Tooyful T-Handle Wrench:
•   Handle Length: 11.5 cm (0.115 m)
•   Key Length: Approximately 10.5 cm (0.105 m)
•   Applied Force: F≈98.1,N (10 kg)
2. Moment of Force Calculation
For Max’s Wheel:
The moment of force (MK) is calculated as:
MK=F⋅R=98.1,N⋅0.125,m≈12.2625,N·m
For Tooyful T-Handle Wrench:
The moment of force (MT) is calculated as:
MT=F⋅LT=98.1,N⋅0.115,m≈11.2915,N·m
3. Difference in Moments
The difference in moments (ΔM) between the two tools is:
ΔM=MK−MT≈12.2625,N·m−11.2915,N·m≈0.971,N·m
4. Effect of Negative Vibrational Forces
Assuming that the 10 kg load is subject to a 1% deformation due to vibrations:
The applied force is 98.1,N, and 1% of this force is:
0.01×98.1,N≈0.981,N
The effective force (Feffective) becomes:
Feffective≈98.1,N−0.981,N≈97.119,N
Calculation of the Effective Moment for the T-Handle Wrench:
Meffective=Feffective⋅LT≈97.119,N⋅0.115,m≈11.1717,N·m
Conclusion
Using an applied force equivalent to a 10 kg load, the analysis yields the following:
•   Moment for Max’s Wheel (SEIKO Socket): approximately 12.2625,N·m
•   Moment for T-Handle Wrench: approximately 11.2915,N·m
•   Difference in Moments: approximately 0.971,N·m
•   Effective Moment for the T-Handle Wrench considering Vibrations: approximately 11.1717,N·m
In conclusion, while there is a slight difference in the moments of force, both tools offer unique characteristics and may be preferred based on specific working conditions. This analysis demonstrates that neither tool is definitively superior; both wrenches present merits and drawbacks in different usage scenarios.
