Answer:
The maximum bending stress in the handlebar extension is ____ N/mm^2
Explanation:
1.Calculate the radius of the handlebars: (32 mm - 3.25 mm) / 2 = 14.875 mm
2.Calculate the maximum bending moment: 75 N * 0.1 m = 7.5 Nm
3.Use the formula for bending stress: σ = M*c/I, where c is the distance from the neutral axis to the outer fiber
4.Calculate the moment of inertia for a solid circular section: I = π/64 * (D_outer^4 - D_inner^4)
5Substitute the values into the formula to find the maximum bending stress
