Instantaneous center:
It is the center about a body moves in planer motion. The velocity of Instantaneous center is zero and Instantaneous center can be lie out side or inside the body. About this center every particle of a body rotates.
From the diagram
Where these two lines will cut then it will the I-Center.Point A and B is moving perpendicular to the point I.
If we take three link link1,link2 and link3 then I center of these three link will be in one straight line It means that they will be co-linear.
Therefore, when the mass is at its equilibrium position (which corresponds to x=0), the velocity of the mass will be maximum.

<span>A mechanical wave is created when a source of energy causes a vibration to travel through a medium
And yeah lol
A mechanical wave is a disturbance in matter that carries energy from one place to another :)
This what you needed? </span>
Answer:
stress = 16.9 MPa
Explanation:
The stress in the cable can be calculated as:

Where F is the force and A is the area. So, the area can be calculated as:

Where r is the radius. Since the radius is half the diameter, the radius is 4.0 mm and the area will be equal to:

Then, replacing the force F by 850 N, and A by 50.24 mm², we get that the stress is equal to:

Therefore, the answer is 16.9 MPa
