1. A load of 25,000 N is applied on a part of radius 15 mm, what is the shear stress,??

Hint, shear stress = load/cross sectional area.

(up to 10 points)

2. If the maximum shear stress,?, is 250MPa and the applied load is 40,000 N what must the area be to ensure it is a safe design?

Hint, load/shear stress = area.

(up to 10 points)

3. A rivet of radius 5 mm has a shear stress maximum of 170 MPa. What force can it withstand before failure?

Hint Shear stress x area = load.

(up to 5 points)

4. If a fuselage has a diameter of 4 m and material thickness of 1 mm, how will its ability to resist shear stress be compared against a fuselage of 8 m with the same thickness?

Hint, think about the ratio of thickness to diameter.
