The brass rod AB is fixed connected at A. When the temperature is T₁-50 °C, there is a 3 mm gap between its end (point B) and the wall C. The cross-sectional area of the rod is 10 cm². Ignore the weight of the bar. The temperature is now increased to T₂-130 °C and the rod AB is pushing against the wall at C. Ebr = 100 GPa, abr = 20 x 10-6/°C Fallow 70 MPa L = 3m A 3 m B/C с 3 mm a. Draw a FBD for when the temperature is increased to T₂ and write down the force balance for this scenario. Call the reactions at FA and FC. Ton =1) und prit brolim volgen Aistis Intelesa si s b. State the compatibility condition and solve for the reactions at A and C.

Classify each of the structures as statically determinate, statically indeterminate, or stable. If stable and indeterminate, specify the degrees of indeterminacy. If unstable, show the reasons. Also specify is Beam, Truss, or Frame.

Determine the degree of determinacy of the structure shown below. Put "-1" if unstable, "O" if determinate and the degree of indeterminacy if indeterminate.

(ii) The bar has a cross-sectional area A, Length L, modulus of elasticity E and coefficient of thermal expansion a. The temperature of the bar changes uniformly along its length from T₁ at A to T at B so that at any point x along the bar T = T₁ + x(T-TA)/L. Determine the force the bar exerts on the rigid walls. Initially the bar has a temperature of TA A A в

Classify each of the plane trusses shown as unstable, statically determinate, or statically indeterminate. If the truss is statically indeterminate, then determine the degree of staticac indeterminacy.
