Answer:
Explanation:
The concept of Hooke's law was applied as it relates to deformation.
The detailed steps and appropriate substitution is as shown in the attached file.
Explanation:
The tear test determines the force required by a material to undergo complete failure when there is already a crack or tear present in it.
With this test we understand a material's resistance to failure when there is already a crack present.
The material which already has a crack is placed in a tensile testing or universal test machine. So, both sides of the material along the crack are pulled until material failure takes place.
Answer:
Option D
160 kHz
Explanation:
Since we must use at least one synchronization bit, total message signal is 15+1=16
The minimum sampling frequency, fs=2fm=2(5)=10 kHz
Bandwith, BW required is given by
BW=Nfs=16(10)=160 kHz
Answer:
Power required to overcome aerodynamic drag is 50.971 KW
Explanation:
For explanation see the picture attached
Answer:

Explanation:
Given
Let the two forces be


and

Required
Determine the resultant force
Resultant force (Fr) is calculated using:

This means that we need to first calculate 
Given that:

In trigonometry:

By comparing the above formula to 


The hypotenuse is calculated as thus:






is then calculated using:


Substitute values for
,
and
in




Take square roots of both sides


<em>Hence, the resultant force is 200N</em>
