Problem No. 2 (100 points) For the Baltimore bridge truss shown below answer the following questions: 1) Calculate Reaction Forces (FBD is already drawn assuming a pin support at A and a roller support at I) (10) 2) What is status of the Truss (determinate or indeterminate)? (10) 3) Obtain ALL the Zero force member (30) 4) Using method of Joints, find force in member PF and PG specify if these forces are in Tension or Compression? (25) 5) Using...
Write the MATLAB code and use the function linsolve() to solve the system of linear equations. Thank you! l Truss A truss is a structure that typically consists of 1. All straight members 2. connected together with pin joints 3. connected only at the ends of the members 4. and all external forces (loads&reactions) must be applied only at the joints. The weights of the members may be neglected. The basic building block of a truss is a triangle. Large...
5. A uniform beam of mass M- 250 kg and length l- 10.0 m is mounted to a wall by a strong hinge and a cable, as shown. A steel block of mass m = 685 kg is placed on the beam a distance x-2.5 m from the hinge. The cable is at an angle -40°, as shown. a. b. c. d. Calculate the tension in the cable. Calculate the horizontal component of the force the hinge exerts on the...

A temporary support steel frame (E - 200 GPa) is made of 30-mm diameter solid circular steel rods (members turnbuckle rods (members BC and AD), all pin connected at the corners A, B, C, and D (see Figure below). The steel frame is braced by two cables AC and BD. A turnbuckle is fitted to cable AC and tightening it will induce tension in cable AC. Determine the largest allowable tension force in cable AC using a factor of safety...
