Click For Summary
The discussion revolves around solving a torque problem involving a two-bar mass structure, with dimensions likely in imperial units. Participants seek clarification on the complete problem statement, including force and calculation units. There is a focus on the torque produced by two forces, questioning whether the counterclockwise torque from one force can balance the clockwise torque from another. The effective lever arm for one of the torques is noted to be shorter, raising doubts about its ability to counteract the larger torque. Understanding the units and dimensions is crucial for accurately solving the problem.

Homework Statement
I have problem on T, is it T is clockwise so the answer is negative?
Relevant Equations
My answer is: M(A)= (Tv x 25)+(Tn x 15)-(300x40)

0=(T sin(5/13)) +(T cos(12/13))- 10200

T=11.27

Please clarify my answer, thank you

Welcome to PF.

Can you please provide the complete problem statement? Is that a 2-bar mass of some sort, welded at the join? It looks like the dimensions are in imperial units (feet, inches), what are the force units in? What are the units in the calculations you have shown?
 
Welcome, Andy! :cool:

Why (300x40)?

Intuitively, do you believe that the CCW torque produced by 11.27 can counteract the CW torque produced by 300?

Note that the effective lever of T is about 0.7 the lever of 300.

Well, technically, it depends on the units, eh? :wink:

I have a question that I couldn’t fully understand its logic. The professor asked us to calculate the shear resistance and moment about the X and Y axis, using the given cross-section and the values of compressive and tensile stresses. I understand how to get the moment, but I’m confused about how to find the shear resistance from these stresses. Could you explain or clarify the method?
