Sagot :

Answer:

Given:

- Punch diameter (d): 20 mm

- Thickness (t): 25 mm

- Shear stress (S)

[tex] \huge \text{Steps:}[/tex]

1. Calculate the Perimeter (P):

[tex]{P = \pi \cdot d = \pi \cdot 20 \text{ mm} = 62.8 \text{ mm}}[/tex]

2. Calculate the Resisting Area:

[tex]{\text{Resisting Area} = P \cdot t = 62.8 \text{ mm} \cdot 25 \text{ mm} = 1570 \text{ mm}^2}[/tex]

3. Calculate the Shear Force (V):

[tex]{V = S \cdot \text{Resisting Area} = S \cdot 1570 \text{ mm}^2}[/tex]

So,

[tex]V = S \cdot 1570 \text{ mm}^2[/tex]

Insert the given value of (S) to find (V).
