If you are sampling a 50Hz signal, what is the minimum sampling rate necessary to prevent aliasing?Why?

horsena [70]

Answer:

100Hz

Explanation:

The minimum sampling rate to prevent aliasing is at least double your sample frequency.

50*2 = 100Hz

This is called the Nyquist Sampling Rate if you wanna learn more about it.

A shaft 70 mm in diameter is being pushed at a speed of 400 mm/s through a bearing sleeve 70.2 mm in diameter and 250 mm long. T

Allushta [10]

Answer:

F=989.6 N

Explanation:

Given that

Diameter of shaft = 70 mm

Diameter of bearing sleeve =70.2 mm

So clearance h=0.1 mm

Speed V= 400 mm/s

Length of shaft = 250 mm

$\nu =0.005\ \frac{m^2}{s}\ , \rho=900\ \frac{kg}{m^3}$

We know that

$\mu =\rho\times\nu$

μ= 900 x 0.005 Pa-s

μ= 4.5 Pa-s

As we know that

From Newton's law of viscosity ,the shear stress given as follows

$\tau =\mu \dfrac{dU}{dy}$

We also know that

Force = shear stress x area

Now by putting the values

$\tau =4.5\times \dfrac{400}{0.1}$

$\tau=18,000 Pa$

So force

F= 18,000 x π x 0.07 x 0.25

F=988.6 N

In this lab, your task is to configure the external vEthernet network adapter with the following IPv6 address: Prefix: 2620:14F0

OverLord2011 [107]

Here is the complete question

You work as the IT administrator for a small corporate network. You need to create a separate subnet to use for testing. The test subnet needs access to the rest of the network through a router, but it should not have any local access to production machines.

You have installed Windows Server 2016 on CorpRTR, which you plan to use to isolate the test segment from the rest of the network. You'll use traditional routing or NAT.

In this lab, your task is to add the necessary role and role services to meet the stated requirements. Do not add unnecessary role services.

Answer & Explanation:

Complete this lab as follows:

1.In the notification area, right-click the Network icon and select Open Network and Sharing Center.

2.On the left, select Change adapter settings.

3.Right-click the vEthernet (External)adapter and select Properties.

4.Select Internet Protocol Version 6 (TCP/IPv6).

5.Select Properties.

6.Select Use the following IPv6 address.

7.In the IPv6 address field, enter 2620:14F0:45EA:0001:192:168:0:10as the IPv6 address.

8.In the Subnet prefix length field, enter 64.

9.Click OK.
