1)Two aluminum alloy plates are clamped together in a bolted assembly with 9 bolts. The first plate has a thickness of 18mm and the second plate has 16mm thickness. The bolt specification is M10x1.5 ISO 9.8 (Metric series, ISO 9.8 is material class). Bolt material is steel and the bolt length is 48 mm. The joint is subject to occasional disassembly for maintenance and should be preloaded accordingly. The applied external load is equally distributed to all bolts. Calculate the maximum external load P... that can be applied to the entire joint without exceeding the proof strength of the bolts. (30 Points) Given Data: Proof strength for ISO 9.8 grade steel bolt is 650 MPa, Tensile stress area for bolt is 58 mm Elasticity modulus of steel is 207 GPa, Elasticity modulus of aluminum alloy is 120 GPa 2)The single-row 02-series Deep-Groove ball bearing with a 55-mm bore is subjected to a 6-kN axial load and a 13-kN radial load. The inner ring rotates at 120 rev/min. (40 Points) a) Calculate the predicted life (in hours) that this Deep-Groove ball bearing could be expected to carry the applied load with a 99 percent reliability. b) Assume that a single-row 02-series Angular Contact ball bearing is required for this application and it should carry the same amount of applied equivalent load with the same realibility (99%) for 5000 h. Suggest a bore diameter for an Angular Contact bearing for this application. Given Data:-In order to check the specifications of 02-series single-row deep-groove and angular-contact ball bearing, see Tables 11-1 and 11-2) -If the inner ring rotates take V as 1, a-3 for ball bearing -Application factor (a)-1, Weibull parameters; x, -0.02, 0-4.459, b=1.483 -Rating life (catalog life) of bearing is 1 million revolutions.
