Calculation Example – Buckling of Column (EC3). Featured

Check the column for buckling according to EC3. HEB300/S275 and axial force NEd=1500KN. The column (L=12m) is pinned at the two far ends (strong axis y-y). The column is pinned every 4m at the weak axis z-z.

Calculation Example – Section Modulus S Featured

A simple beam pinned at two ends is loaded as shown in the figure. Calculate the required section modulus S if σallow =1500 ΚΝ/m2, L =24 m, P =2000 KN, and q = 400 KN/m.

Calculation Example – Friction Featured

The friction coefficient is c1=0.2 between two bodies A,B. The friction coefficient is c2=0.18 between body B and the ground. If mass mA=0.5kgr and mB=1kgr , what is the minimum force P so that the two bodies start sliding?(we consider that there is no friction at the rope).

A single point with mass m is vibrating harmonically. The displacement x from point of balance is governed by the differential equation

Calculation Example – Critical load. Featured

A solid rod has a diameter of 20 mm and is 600 mm long. It is made of a material that can be modeled by the stress–strain diagram shown in the figure below. If it is used as a pin-supported column, determine the critical load.
