Bolt A has higher pre-load than bolt. Then. everything else being the same a) Bolt A fails before bolt B b) Bolt B fails before bolt A c) Both bolts fail at the same time d) None 8 20) For two springs in parallel subject to loading and observing the deflection, we can conclude a) Deflections add and forces remains constant b) Forces add and deflection remains constant c) Both deflections and forces add d) Both deflections and forces remain constant 6) Which of the following is measure of stiffness? a) Resilience b) Modulus of plasticity c) Modulus of elasticity d) Toughness 7) Hardness is a) Surface property b) Resistance to abrasion c) Depends upon resistance to plastic deformation of the material d) All of the mentioned 8) Fatigue failure is time dependent failure. a) True b) False 9) In which of the following case stress concentration factor is ignored? a) Ductile material under fluctuating load b) Ductile material under static load c) Brittle material under static load d) Brittle material under fluctuating load 10) Which of the following reduces the stress concentration at a shoulder supporting a bearing with a sharp radius? a) Large radius undercut into the shoulder b) Large radius relief groove into the back of the shoulder c) Large radius relief groove into the stall diameter d) Each of the mentioned i 11) Angular contact hearing can take thrust as well as radial loads. a) True b) False 12) Which of the following function can the spring perform? a) Store energy b) Absorb shock c) Measure force d) All of the mentioned 13) Helical torsion spring is subjected to torsional shear stresses. a) True b) False 14) An idler gear is a gear that will remain still in a gear train while other gears are engaged and tum. a) True b) False 15) If spring index-2.5, what can be concluded about stresses in the wire? a) They are moderate b) They are negligible c) They are high d) Cannot be determined 7 16) A power screw is only used to convert rotary motion into linear motion and not for transmitting power. a) Truc b) False 17) If you double the wire diameter of a spring, keeping everything else the same then the stiffness a) increases by a factor of 16 b) decreases by a factor of 16 c) increases by a factor of 2 d) decreases by a factor of 2 18) What is an appropriate unit for Spring constant? a) m/N b) N/kg c) Ibm/in d) lbf/in 19) There two bolts A and B used in two different situations with same static and fatigue loading conditions.
