Calculate the maximal friction force for a parked car between the rubber tires and a wet street. Assume the car’s mass is 1600 k
NikAS [45]

Answer:

Fr=12544N

Explanation:

1. Find the equation of eht maximal friction force:

The maximal friction force is given by the equation Fr=usmg, where μs is the static friction coefficient, m is the car´s mass and g is the gravitational force.

2. Replace values in the equation to find the answer:

Fr=0.8*1600kg*9.8\frac{m}{s^{2}}

Fr=12544N

Elevated water tanks are used in a municipal water distribution system to provide adequate pressure. Compute the height (h) of t
Lemur [1.5K]

Answer:

a)  h = 53.8 m,  b)   h_minimum = 28 m, h_maximum = 63.3 m

Explanation:

a) For this exercise let's use Bernoulli's equation.

The subscript 1 is for the tank and the subscript for the building

          P₁ + ½ ρ g v₁² + ρ g y₁ = P₂ + ½ ρ g v₂² + ρ g y₂

In general, the water tanks are open to the atmosphere, so P1 = Patm, also the tanks are very large so the speed of the water surface is very small v₁=0 and as they give us the precious static, this it is when the keys are closed so the output velocity is zero, v₂= 0. The height of the floors in a building is y₂ = 12 m

           

we substitute in Bernoulli's equation

         P_{atm} + 0 + ρ g h = P₂ + 0 + ρ g y₂

         h = \frac{(P_2 - P_{atm}) + \rho \ g \ y_2}{\rho \ g}

         h = \frac{\Delta P}{\rho g} + y₂

indicate that the value of ΔP = 410 10³ Pa

       

we calculate

           h = 410 10³ / (1000 9.8) + 12

           h = 53.8 m

b) ask for the height range for the minimum and maximum pressure

            h =\frac{\Delta P}{\rho g} ΔP / rho g

minimum

           h_minimum = 275 103/1000 9.8

           h_minimum = 28 m

maximums

           h_maximo = 620 103/1000 9.8

           h_maximum = 63.3 m
