What is the pressure due to a man weighing 80 kg standing on his feet? Area of his feet 160 Sq. Cm
recall the definition of
pressure = force/area
To calculate the pressure due to the man's weight on his feet, we can use the formula:
Pressure = Force / Area
First, let's find the force exerted by the man's weight. The force can be calculated using the formula:
Force = Mass * Gravity
where the mass is given as 80 kg and the standard gravity is approximately 9.8 m/s^2.
Force = 80 kg * 9.8 m/s^2 = 784 Newtons
Now, let's convert the area from square centimeters to square meters:
Area = 160 cm^2 = 160 / 10,000 m^2 = 0.016 m^2
Finally, we can calculate the pressure:
Pressure = Force / Area = 784 N / 0.016 m^2 = 49,000 Pascal
Therefore, the pressure due to the man's weight is 49,000 Pascal.
