The answer is Compressional.
Compression is a stress that pushes and squeezes rocks together. This causes the rock to bend or fracture.
Tension is a stress that pulls rocks apart. Shear stress occurs when the rocks are moving parallel but opposite of each other pushing rocks at different directions. Gravitational stress is stress induced by gravity.
Answer:
![\theta=156.81^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D156.81%5E%7B%5Ccirc%7D)
Explanation:
It is given that,
Force due to rope 1, ![F_x=700\ N](https://tex.z-dn.net/?f=F_x%3D700%5C%20N)
Force due to rope 2, ![F_y=300\ N](https://tex.z-dn.net/?f=F_y%3D300%5C%20N)
Let
is the angle must a third rope tension be applied in order to keep the boat at rest. It can be given by :
![tan\theta=\dfrac{F_y}{F_x}](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cdfrac%7BF_y%7D%7BF_x%7D)
![tan\theta=\dfrac{300}{700}](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cdfrac%7B300%7D%7B700%7D)
![\theta=23.19^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D23.19%5E%7B%5Ccirc%7D)
The angle clockwise from the positive x-axis will be equal to,
![\theta=180-23.19](https://tex.z-dn.net/?f=%5Ctheta%3D180-23.19)
![\theta=156.81^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D156.81%5E%7B%5Ccirc%7D)
So, the angle must a third rope tension be applied in order to keep the boat at rest is 156.81 degrees. Hence, this is the required solution.
