A thrust bearing setup is shown in the figure. Failure could occur by a normal, compressive stress failure in the bar with diameter, d; a shear stress failure of the thrust collar with thickness, t; and a bearing stress failure of the thrust collar, with an outer diameter of Dollar, against the supporting plate. The load applied is P-3000 lb. Assume the plate will not fail. Material Properties - Maximum Allowable Stress Levels Bar Normal Stress Jallow 4 ksi Thrust Collar Shear Stress Thrust Collar Bearing Stress Tallow = 2 ksi Jallow = 2 ksi Determine the following considering each possible failure states: a) The required diameter, d, of the bar needed to prevent a Normal Stress Failure of the bar. b) The required thickness, t, of the thrust collar to prevent a Punching Shear Failure of the collar. c) The required Deoller of the thrust collar to prevent a Bearing Stress Failure of the collar. Thrust collar Problem 3: A bridge suspender consists of a cable that passes over the main cable (see figure) and is used to support a bridge deck, which if far, far below. The suspender is 'pinched' by a metal tie, which is prevented from moving by clamps. The metal tie serves to change the cable direction from inclined to vertical. The vertical tension force in the cable is P-130 kN. The force in the cable is NOT the same throughout the cable length due to using the horizontal tie in the system. The allowable normal stress of the tie material is Gallow-80 MPa and if this stress is exceeded the tie will fail. The allowable normal stress of the cable is allow 150 MPa. Take 0.75* a) Determine the minimum required cross-sectional area of the tie bar. b) Determine the minimum required diameter of the cable.
