Torque hacks – But how can I trust my physics calculations?

Goal: Tighten 10Nm #Golf2 valve cover bolts

Problem: Torque wrench 42–210Nm

Solution: Use 9.26kg water container to pull a string attached to a wrench r=0.11m.

Calculation

Mass = 10Nm / (9.81911 m/s^2 * 0.11m)

Rewrite: Newton = ( kg*m ) / s²

Mass = 10 (kg*m²)/s² / (9.81911 m/s² * 0.11m)

Mass = 9.26kg

of witch water container is 0.907g and the cord 52g, leaving 8.3l for the water.

But OMG, the 9.3kg FEELS SO HEAVY that it is hard to believe the M6 bolts won't tear the aluminium motor block :O
