if a tank filled with water contains a block and the height of the water above point A within the block is 0.6meter, what's the
Fittoniya [83]
The pressure exerted by a fluid solely relies on the depth or height of the fluid, its density, and the gravitational constant. These three are related in the equation:

Pressure = density x g x height

In the problem, point A is within the block inside the tank. The water above the block is assumed to be 0.6 meters. This gives a point A pressure of:

P = 1000 kg/m^3 * 9.81 m/s^2 * 0.6 m = 5,886 Pa or 5.88KPa

Beam design what is the maximum code-allowable floor beam deflection under the given live load?
Irina18 [472]

According to I.S. standards, the maximum deflection should typically not be greater than 1/325 of the span.

<h3>What is Beam deflection?</h3>

A beam is a long segment of a body that can support a weight while defying bending. Beam deflection is the term for the movement of a beam when a force is applied to it in a certain direction.

The beam has the ability to be bent or shifted from its initial position. The deflection is represented by this distance along each member point.

The amount of displacement that a certain structural member may experience with the aid of a sizable amount of load is known as deflection. It may also be known as the angle or the separation. The slope of the deflected form of the body under a load directly influences the distance of deflection of a member under that force.

A 70kg car drives through a curve with radius 50m. What is the minimum angle the road should be tilted to keep the car on the ro
worty [1.4K]

when car moves along a circular path then centripetal force for taking turn will be provided by the component of normal force

Let the road is tilted by some angle

so force equations are given as

F_n cos\theta = mg

F_n sin\theta = \frac{mv^2}{R}

now divide two equations

tan\theta = \frac{v^2}{Rg}

now as it is given to us that

v = 80 km/h

v = 80* \frac{5}{18} = 22.2 m/s

R = 50 m

now we have

tan\theta = \frac{22.2^2}{50*9.8}

tan\theta = 1

\theta = tan^{-1}1

\theta = 45^0

so it is inclined at an angle of 45 degree

What does it mean when work is positive?
Degger [83]

Answer:

To have a positive job, the two vectors must have the same direction

Explanation:

Work is a scalar defined as the scalar product of two vectors, the froce and the displacement. To have a positive job, the two vectors must have  

collinear and that their arrows point in the same direction.

You can also appreciate this from the work equation

       W = F. r

bold indicate vector

      W = F  r cos θ

 

With θ the angle between force and displacement
