XG Le An A-36 steel rod of 15-mm diameter and 1,2-m length is held snuggle (but without any initial stresses) between rigid walls by the arrangement shown. The threaded portion of the rod at B has a pitch of 1.5-mm/thread (or an advance of 1.5-mm per revolution of the nut). a. Using a safety factor of 2.5 against yielding, calculate the maximum number of turns that the nut may undergo before the rod yields. b. Calculate the maximum number of turns that the nut may undergo before the 12-mm diameter bolt at A shears. The allowable shear stress for the bolt is 100 MPa. \ turn =P gr 157 rat Trev yr osemea wae 190 Mes ~ (eS em Bio men 9 9s Ty RN poe Sere a r m i - EF a Sheer Gane : ie == e \ bol¥ (100 mea) AACN G.or my) * 42 ; \ Generated by CamScanner from intsig.com
