The minimum thickness of a base plate, ts in case of slab base can be calculated by the formula

\({t_s} = \sqrt {2.5w\left( {{a^2} - 0.3{b^2}} \right){f_y}/{\gamma _m}_0} \)

\({t_s} = \sqrt {2.5w({b^2} - 0.3{a^2}){f_y}/{\gamma _{{m_0}}}} \)

\({t_s} = \sqrt {2.5w\left( {{b^2} - 0.3{b^2}} \right){\gamma _m}_0/{f_y}} \)

\({t_s} = \sqrt {2.5w\left( {{a^2} - 0.3{b^2}} \right){\gamma _m}_0/{f_y}} \)

1.	The minimum thickness of a base plate, ts in case of slab base can be calculated by the formula
A.	\({t_s} = \sqrt {2.5w({b^2} - 0.3{a^2}){f_y}/{\gamma _{{m_0}}}} \)
B.	\({t_s} = \sqrt {2.5w\left( {{b^2} - 0.3{b^2}} \right){\gamma _m}_0/{f_y}} \)
C.	\({t_s} = \sqrt {2.5w\left( {{a^2} - 0.3{b^2}} \right){\gamma _m}_0/{f_y}} \)
D.	\({t_s} = \sqrt {2.5w\left( {{a^2} - 0.3{b^2}} \right){f_y}/{\gamma _m}_0} \)
Answer» D. \({t_s} = \sqrt {2.5w\left( {{a^2} - 0.3{b^2}} \right){f_y}/{\gamma _m}_0} \)
