Consider the following statements associated with variable loading of bolts
1. Smaller the stiffness constant larger will be the external load by the bolts
2. Greater the pretension lesser will be the value of the alternating load carried by the bolts
3. In variable loading component will variable load is more dangerous than component with static load
4. A high value of pretension is undesirble against fatigue failure
Which of these statements are correct?
(a) 1,2,3 and 4 (b) 2 and 3 only
(c) 3 and 4 only (d) 1 and 2 only
