Pipe cutter is fixed on a pipe, with 3 forces acting on the pipe.

[BaLTHEBEAST]

The figure shows a pipe cutter clamped on a pipe. 3 Forces are acting on the pipe. These forces must be identified. These forces have different directions. The pipe is estimated to be in an equlibrium state of force , so it does not break the pipe, instead it holds the pipe tightly.

I will attach 2 pictures with the questions below. Please check and help me find a way to solve these questions.
I just need a hint or a way to start the calculation, and to find the 3 forces and the angles of the forces as well.

The question did not provide any extra informations, so please help me. This is a hard question..

You have my advanced gratitude. Thank you so much!

F_net = ma

I think that F = ma is premature for this problem. No statement of the requirements for equilibrium has been provided by the original poster for the forces exerted by the pipe cutter on the pipe. Without knowing the equilibrium relationship, then the second part of the question cannot be done.

Perhaps, but I am just trying to get the OP to start thinking about what is going on.

No statement of the requirements for equilibrium has been provided by the original poster for the forces exerted by the pipe cutter on the pipe.

The problem statement says "The pipe is estimated to be in an equlibrium state of force", which is a statement about the acceleration or sum of the forces.

Without knowing the equilibrium relationship, then the second part of the question cannot be done.

Yes it can. The equilibrium relationship is a simple statement about the vector sum of the forces. But first let's let the OP respond with some attempt at solving the problem. The OP has already been given advice on solving https://www.physicsforums.com/showthread.php?t=492657", which would work here.

The first question needs explanation, ignore it. I am done with question one...

The second question requires a tangent line to the circle.. tan θ = Opposite/Adjacent..
I figured it out.
We have to use the lengths given. For example to get an angle in the diagram, We have to form a triangle in the circle given, Therefore, it will be tan θ = 10/17 ... According to the information given :D

And no, F=ma cannot be used in this diagram, it doesn't say there is acceleration.

Anyways I appreciate your help! THANK YOU!

wat is the explanation of 1st question ?

 

[yonkwang]

are you from psdc? :) I am batch 20 group 3. you:)

As it says in the problem statement:

"The pipe is estimated to be in an equlibrium state..."​

Think about what that means, then post your attempt (does not necessarily have to be complete and correct) at solving the problem.

tan θ = 10/17 that is what sin would be in that triangle, tan would be 10/13.7477
