Homework Statement
In my book , i was told that when the shear stress turn a plane of element clockwise , then the shear stress is positive ,
In this question , we can notice the shear stress of 40 will turn the plane clockwise , why the author plot the stress at A = (80,-40) ? Shouldn't it be at A = (80,40) ?
