What is velocity ratio ?

1 answer:

5 0

The ratio of the distance moved by the point at which the effort is applied in a simple machine to the distance moved by the point at which the load is applied, in the same time. In the case of an ideal (frictionless and weightless) machine, velocity ratio = mechanical advantage. Velocity ratio is sometimes called distance ratio.

Find the pressure exerted by a force 8000 newton's on an area of 25m^2. Give your answer in newton's/n^2

Vanyuwa [196]

The pressure exerted by this force is equal to 320 $N/m^2$ .

<u>Given the following data:</u>

Force = 8000 Newton.

Area = 25 $m^2$ .

To calculate the pressure exerted by this force:

<h3>How to calculate pressure.</h3>

Mathematically, pressure is given by this formula:

$P=\frac{F}{A}$

<u>Where:</u>

P is the pressure.

F is the force.

A is the area.

Substituting the given parameters into the formula, we have:

$P = \frac{8000}{25}$

P = 320 $N/m^2$ .

Answer:

$F=\rho_LAdg$

Explanation:

The buoyant force F is equal to the weight of the displaced fluid. The weight of the displaced fluid is $W=m_dg$ , where $m_d$ is the mass of the displaced fluid. The mass of the displaced fluid is $m_d=\rho_LV_d$ , where $\rho_L$ is the density of the fluid and $V_d$ is the displaced volume, which is equal to the submerged volume of the cilinder $V_d=V_s=Ad$ .
