Bolt shear stress

Bolt shear stress

Bolt shear stress

(OP)
Hi folks

There is a rack in work which is held by 6 bolts on both ends, if this is turned upside down and supported by only 4 bolts each end, how do i calculate if the 4 bolts will support the load.

The bolts are 19mm diameter and the load will be approx 3 pallets weighing at least 2100kg each

Thanks in advance.

Hi Killian12345

We need a sketch of you're actual rack including some dimensions on size, what the bolts are fastened into, where the loads are applied etc.

RE: Bolt shear stress

Every grade of bolt has it's allowable load stated somewhere, for instance an M16 grade 4.6 bolt will take around 34kn tensile & 23 Kn in shear
What you need to know is what loads are coming on the bolts

Why does this sound like a homework question?  But, I'll give you the benefit of doubt; did you check your Shigley book?
