Answer:
Explanation:
Diagrams of Shear force show the total shear force at each cross section of a structural member throughout the length of the beam or structural member. However, that force is not equally distributed throughout the individual cross section of the structural member. The maximum shear stress is referred to as the maximum concentrated shear force in a small area.
The Maximum Shear Stress theory states that failure occurs when the
maximum shear stress from the total of principal stresses equals
or exceeds the value obtained for the shear stress at yielding in the
uniaxial tensile test.
At yielding, in an uni-axial test, the principal stresses is given as:
σ=Sy; -
σ2 = 0 and σ3 = 0.
Therefore the shear strength at yielding
Ssy =[σ- (σ2 or σ3=0)]/2. Therefore Ssy = Sy/2
From the information given:
Tmax= σ1 - σ2/2
Tmax= 450-200/2
Tmax= 250/2
Tmax= 125 kpa

Answer:
Reflection
Explanation:
The specific behavior of light that will be essential to ensure the success of your design is "Reflection". This is because light maze makes use of a mirror and it's the light that is reflected that we see with our eyes. Also, the manner in which light is reflected off objects will affect the colors that are reflected as well.
