Re: rotation at bearings

[Subject Prev][Subject Next][Thread Prev][Thread Next]
This solution may be a bit disingenuous, but have you considered tightening your holes on the "fixed" end to 1-1/8" slotted, with the total slot length of 1-3/8"? Will this throw off your assembly tolerances?

Indeed, the ø1? anchor bolts of the subject bridges are located in ø1-3/8? baseplate holes (3/8? gap). According to my own 3D analysis , the maximum movement of the bridge at the supports due to the horizontal-plane rotation under the transverse force of a 100 MPH wind is 0.18? << 3/8?. This means that actual ?pins? and lengthwise reactions (due to transverse forces) in those bearings will never materialize.
