Question 2
The uniformly distributed force f (unit: N/m) is applied along the axis of the bar, and a
concentrated force P (unit: N) is applied at the free end of the bar. The bar has a constant
Young's modulus E and cross-section area A. Find the stretch of the bar: (a). at the free
end of the bar; (b). at the center of the bar. (Expressing all the resulta with E, A, L, f,
and P).
