Note: 1, this watch USES SP = 1/2d2 formula to calculate the total amount of broken pull, the diameter d is the UK, that is, 1 British point = 3.175 mm.
2 = 1/2 (= 1/2) 2 * 0.82
3, 0.82 is the coefficient of this wire rope
A prediction, the steel wire rope, the safety load limit load (using the formula: SP = 1/2 d2, where d is the diameter of wire rope, the unit must be turned into the points and the points 1 = 3.175 mm; 0.81, 0.82 for scaling factor values; for safety factor K values) :
The current one is a 6 x 37 steel wire rope with a diameter of 21 mm, calculating the breaking pull of the wire rope and allowing the pull force.
Break tension SP = 1/2d2 * 0.82
Is equal to 1/2 times (21 is 3.175) 2 times 0.82
Is equal to 1/2 times 43.75 times 0.82
= 17.94 (t)
Allow the tension S = SP to be equal to 17.94 and the 6 = 2.99 (t)
The current one is a 6 x 29 + 1 steel wire rope with a diameter of 33 mm, calculating the breaking pull of the wire rope and allowing the pull force.
