Modulus Screw Shear Shear modulus

AI Thread Summary

The discussion centers on calculating the shear modulus of a screw that breaks at 39 ft/lbs of torque with a shaft diameter of 0.130 inches. Participants suggest using the formula f=T/l and the relationship l/L=angle to derive the answer. The focus is on applying these formulas to determine the material's shear modulus effectively. Accurate calculations are essential for understanding the screw's performance under stress. The thread emphasizes the importance of material properties in engineering applications.

I have a screw that is used in our plant that is rated to break at 39 ft/lbs of torque.
The diameter of the shaft is .130 inches.
What is the shear modulus of the material that is being used.
Thanks

maybe if you use f=T/l and l/L=angle you will get the ans

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
