### K-Truss Analysis Using the Method of Sections**Questions:**1. **(a)** Establish whether the truss is statically determinate. Justify your answer mathematically.2. **(b)** Determine the reactions at the supports A and K.3. **(c)** Apply cuts 1 and 2 to determine the forces in members DE, QE, and OP. State whether these members are in compression or tension.**Diagram:**The diagram is of a K-truss structure. Key features include:- Multiple panels labeled C through I.- Support reactions are located at points A and K.- External loads applied: 1800 lb at C, 1000 lb at P, 1200 lb at O, and 2000 lb at M.- The truss consists of six panels, each 4 feet wide.- Points P and O are highlighted with red cuts labeled ① and ②.---### Problem 2: Antenna Support Truss Analysis**Description:**An antenna and its supporting structure weigh 300 lb with the mass center at point C. It's assumed that 1/4 of the weight is supported by pins at A and B, with the rest carried by an identical truss behind the one shown.**Questions:**1. **(a)** Establish whether the truss is statically determinate. Justify your answer mathematically.2. **(b)** Compute the horizontal components of the pin reactions at A and B.3. **(c)** Find the forces in members DF, DG, AH, and AB. Identify which force depends on the assumption about "1/4 of the weight".**Diagram:**Similar to the K-truss, featuring multiple triangles typically used for stability. Forces are distributed across its nodes.---**Note:** Detailed mathematical calculations are necessary to resolve the queries in both problems.
