Question

Колонна, площадь основания которой 0,5 м квадратных оказывает на грунт давление 5 МПа С какой силой давит колонны на грунт?

Answer 1

р=Fд/ S

Fд- сила давления

S-площадь тела

Fд= р* S

Fд= 5*10^6* 0,5=2,5*10^6(Н)=2,2МН  

Ответ: Fд=2,5МН   

Answer 2

Calculation of the Force Exerted by the Column on the Ground

To calculate the force exerted by the column on the ground, we need to use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

Given that the area of the base of the column is 0.5 square meters (0.5 m^2) and the pressure exerted on the ground is 5 megapascals (5 MPa), we can rearrange the formula to solve for force:

Force (F) = Pressure (P) x Area (A)

Substituting the given values:

Force (F) = 5 MPa x 0.5 m^2

Now we can calculate the force:

Force (F) = 2.5 meganewtons (MN)

Therefore, the column exerts a force of 2.5 meganewtons on the ground.
