An ordinary workshop grindstone has a radius of 7.50 cm and rotates at 6500 rev/min. (a) Calculate the magnitude of the centripe
jonny [76]

To solve this problem it is necessary to apply the concepts related to the relationship between tangential velocity and centripetal velocity, as well as the kinematic equations of angular motion. By definition we know that the direction of centripetal acceleration is perpendicular to the direction of tangential velocity, therefore:

a_c= \frac{v^2}{r}=r\omega^2

Where,

V = the linear speed

r = Radius

\omega = Angular speed

The angular speed is given by

\omega =6500\frac{rev}{min}(\frac{2\pi rad}{1 rev})(\frac{1 min}{60s})

\omega = 680.6784 rad/s.

Replacing at our first equation we have that the centripetal acceleration would be

a_c = r\omega^2

a_c = (0.0750)(680.6784)^2

a_c = 34 749.23 m/s^2

To transform it into multiples of the earth's gravity which is given as 9.8m / s the equivalent of 1g.

a_c =34749.23 \frac{m}{s^2} (1\frac{g}{9.8m/s^2})

a_c = 3545.84g

PART B) Now the linear speed would be subject to:

v = \omega r

v= (680.6784)(0.0750)

v=51.05 m/s

Therefore the linear speed of a point on its edge is 51.05m/s

The pressure extered by fluid at any given depth is exerted _____ in all directions
Blababa [14]

The pressure exerted by fluid at any given depth is exerted equally in all directions.

<h3><u>Explanation:</u></h3>

Pressure is defined as the force per unit area. Hydraulic force is the force that is exerted by liquid to a particle which is present somewhere inside the liquid. This pressure is exerted by the liquid particles from each part of the of the whole mass.

As far as the upper particles are concerned, the liquid exerts the force due to gravity, which acts downwards. Similarly, the particles which are down to the particle in liquid gives the reaction force which is based on Newton's third law of motion. This makes the force acts from all sides.

This is the reason why a particle which is submerged stays still, as there's no unbalanced force which can turn the particle.
