1.Easy

A column of length L made of aluminium is pinned at both ends. Using Euler’s formula, find its critical buckling load P_cr.

L = 1.5 mE = 70 GPa (aluminium)b × h = 30 × 50 mm

P_cr = kN

2.Easy

A column of length L made of steel is pinned at both ends. Using Euler’s formula, find its critical buckling load P_cr.

L = 2 mE = 200 GPa (steel)d = 20 mm

P_cr = kN

3.Medium

A column of length L made of aluminium is fixed at the base and pinned at the top. Using Euler’s formula, find its critical buckling load P_cr.

L = 1 mE = 70 GPa (aluminium)b × h = 25 × 50 mm

P_cr = kN

4.Medium

A column of length L made of aluminium is fixed at the base and free at the top. Using Euler’s formula, find its critical buckling load P_cr.

L = 2 mE = 70 GPa (aluminium)b × h = 30 × 40 mm

P_cr = kN

5.Hard

A column of length L made of steel is fixed at the base and pinned at the top. Find its slenderness and the critical buckling stress σ_cr from Euler’s formula.

L = 2 mE = 200 GPa (steel)d = 30 mm

σ_cr = MPa

6.Hard

A column of length L made of steel is fixed at the base and free at the top. Find its slenderness and the critical buckling stress σ_cr from Euler’s formula.

L = 2.5 mE = 200 GPa (steel)d = 50 mm

σ_cr = MPa

Answer key

1. P_cr = 34.54 kN
2. P_cr = 3.876 kN
3. P_cr = 91.79 kN
4. P_cr = 3.886 kN
5. σ_cr = 56.65 MPa
6. σ_cr = 12.34 MPa
