Question: The truss, shown in the Figure, is subjected to the weight W and supported by the pins connected to the ground at point A and J as well as the cable. The weight W is given as W = 1000(a +b+c) Newtons and the dimension d is measured as d=1+a+0.2b + 0.5c meters. Then please evaluate the forces in members CB, CG and FG by using method of sections only once. Note that the member EC is directed vertical and the pulley diameters are negligible. Use of method of joints to evaluate the member forces is not allowed.

Atomic diffusion in solids

In material science, diffusion can take place in solid, liquid, and gases. In solids, atomic diffusion can take place with the help of thermally activated and randomly vibrating atoms. The atomic diffusion in solids is complex and very slow in comparison to atomic diffusion in liquids and gases because the interatomic distance between the atoms is smaller in solids as compared to liquids and gases.
