Bar subjected to gravity load (two segments) The bar in the figure has constant cross sectional area . The top half of the bar is made of material with mass density , and Young’s modulus . The bottom half of the bar is made of material with density and Yo...

I read but I don't understand because some guys talking on one question and some guys talking on other question at the same time.

Please help me, anyone figured out problem 3 and 4?

problem 4_2 part :1 A load W=2 kN is applied vertically to joint C of truss ABCDE as indicated. plz help

E4_1? All the bars in truss ABC have constant cross section and are made of a homogeneous linear elastic material. Under the effect of a 1 kN horizontal load applied at B , the pin at A is observed to displace to the right by 6 cm. Use the method of joint...
