A circular footing with diameter $2\mathrm{.}2$m is found on a saturated stiff overconsolidated clay with ysat$=19,$ undrained shear strength cu$=100$kPa and effective shear strength parameters c$=15$kPa and $20$ degrees The water table coincides with the surface of the soil and a uniform surcharge equal to $10$kPa is applied on the soil surface. Calculate the short$-$term and long$-$term

safety factor using the Meyerhof methodology for a vertical load equal to $1000$kN $($it includes the

weight of the footing$).$
