Answer» ure EXERTED by one feet = 240 paForce by feet on the land = 60NArea occupied by the feet = 0.25 m² _______________________As we know that , ☞ PRESSURE = Force ÷ AREA By the given INFORMATION ,♦ Force on each feet = 60/2 = 30N ♦ Area occupied by one feet = 0.25/2 = 0.125m²So , ⇒ Pressure = 30 ÷ 0.125 ⇒ Pressure = 30 ÷ 125/1000 ⇒ Pressure = 30 ÷ 25/200 ⇒ Pressure = 30 ÷ 5/40 ⇒ Pressure = 30 ÷ 1/8 ⇒ Pressure = 30 × 8 ⇒ Pressure = 240 N/m² or pa |
