From the given truss shown, computethe forces in members BC, CD, and CG. Given the allowable shear stress of 70 MPa and the allowable bearing stress of 140 MPa.  Compute how many 10 mm-diameter rivets are required to fasten member CG to the gusset plate.

Using the CREMONA method, determine the forces and types of stress in the bars and analyze them.

Determine the member stresses in members AB, AC, AD, BC, and BD if the cross-sectional area for all members is 800 mm². Note: You may use any method 3 m ון 2 - 3 m 4 m 5 m 6 kN Situation 4: Terminologies 1. A structural element that carries a load that is applied transverse (perpendicular) to its length and the top fibers are in compression; the bottom fibers are in tension. 2. A structural element that is composed of smaller structural members typically configured in triangular arrangements. 3. Codes that specify combinations of loads that must be considered in the design of structures in the Philippines? 4. How many equations of equilibrium are there in space structures? 5. These are the forces exerted by supports on the structure and tend to prevent its motion and keep it in equilibrium. 6. The internal force in the direction of or parallel to the centroidal axis of the beam 7. The internal force in the direction perpendicular to the centroidal axis

Two steel rods are welded together (see figure);the seam is oriented at angle θ = 50°. The stresses onthe rotated element are σ x1 = 10 ksi,  σy1 = -12 ksi,and τx1y1 = -5 ksi. Find the state of plane stress onthe element if it is rotated clockwise to align the x1axis with the longitudinal axis of the rods.
