1.	An eyebolt is to be made out of steel having an ultimate tensile strength of 500 N/mm2. If the load to be lifted using this eyebolt is 500 kgf then using a factor of safety of 2 find the core diameter (minor diameter) of the thread for eyebolt.
A.	\(4\sqrt{\frac{5}{\pi}}\)mm
B.	\(5\sqrt{\frac{5}{\pi}}\) mm
C.	\(15\sqrt{\frac{5}{\pi}}\) mm
D.	\(2\sqrt{\frac{5}{\pi}}\)mm
Answer» B. \(5\sqrt{\frac{5}{\pi}}\) mm
