Will be screwed only one time. I want to know how it will work without helicoil threads. Bolt diameter M12x50 DIN 912, will be installed without grease. I calculated before - the shear stresses in the bolt and aluminum plate are less than the maximum allowable stresses. Also I heard, that if you...

I need advice how to calculate thread pull out in aluminium 6063-T6. 12 bolts screwed into an aluminium plate (thread depth 25 mm) must withstand a load of 350 kg. Thanks in advance

Thanks for help. I calculated static moment and its much more larger than torque I calculated through moment of Inertia. As I understood, bigger value will be the peak moment? I will use worm gearbox, ratio 100. Output torque is 750 Nm

I need to know how to calculate torque, if center of mass of workpiece will be higher than shaft center of mass (+50mm). And if center of mass of workpiece will be on the same axis with shaft, then how do I need to calculate? F*r?

Weight of loading plate is 50 kg (aluminium). Max weight (of workpiece) is 400 kg.

I'm designing loading mechanism of new machine and need to know what the torque will be. Here is the sketch of my mechanism. Distance from centre of shaft to the top of loading table is 200mm. Distance from the centre of mass of workpiece to centre of the shaft 50 mm. Max load is 400 kg. Weight...
